Overview
The ZJIES1000D-22T4GB series is an unmanaged industrial Fast Ethernet DIN-rail switch offering up to 22 × 10/100Base-T copper ports plus 4 × 1000Base-X SFP Gigabit uplink slots — the highest Fast Ethernet port count in the ZJIES1000D unmanaged line. It is plug-and-play with no configuration required, uses store-and-forward switching with an 8K MAC address table, and ships in a compact IP40 metal enclosure (64×174×143 mm) for DIN-rail or wall mounting. Powered by AC 220V (100–240V) single input or DC 24V (12–36V) / 48V (36–56V) redundant dual input with reverse-polarity and overload protection, it operates from -40 to +75°C — suited for sites that need to aggregate a large number of near-end 100M devices onto Gigabit fiber uplinks.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
High-Density Fast Ethernet Aggregation with Quad-Gigabit SFP Uplink22 × 10/100Base-T copper ports — the highest Fast Ethernet port count in the ZJIES1000D unmanaged series — feed into 4 × 1000Base-X SFP slots for gigabit uplink, ideal for aggregating a large cluster of 100M edge devices onto a Gigabit backbone.
Field-Configurable SFP Optics, Single-Mode Reach to 120 kmAll 4 uplink ports are SFP slots rather than fixed fiber, so single-mode or multimode, SC/ST/FC connector, and single-/dual-fiber optics are chosen per slot — single-mode transceivers reach 20/40/60/120 km, the longest option in this switch family.
DIN-Rail Cabinet Installation Across Three Power OptionsAC 220V (100–240V) single input, DC 24V (12–36V) redundant, or DC 48V (36–56V) redundant — the same 64×174×143 mm DIN-rail (wall-mount optional) enclosure fits directly into a standard electrical cabinet regardless of which supply is on site.
Extreme-Temperature Outdoor Cabinet DeploymentA -40 to +75°C operating range (-40 to +85°C storage) plus EN61000-4 Level 3 EMC immunity suit unheated roadside cabinets and unconditioned equipment rooms where 22 field devices need aggregation.
Large-Scale Access-Control & Sensor Panel AggregationWith 22 individually switched 100M ports, one unit can wire up a building or campus floor's worth of access-control panels, alarm points, or environmental sensors without daisy-chaining multiple smaller switches.
Dual Redundant DC Input for Unattended Remote SitesThe DC 24V (12–36V) or DC 48V (36–56V) variants take dual redundant input with reverse-polarity and overload protection, keeping an unattended substation or pump-station cabinet online if one feed fails.
Not a good fit if:
- Unmanaged fixed-configuration switch — no VLAN, QoS, or RSTP/ERPS ring-redundancy management; choose a managed model if the network needs software control.
- No PoE output on any of the 22 copper ports — cameras, APs, or IP phones needing PoE power require an external injector or a PoE-capable switch.
- The 4 uplink ports are SFP slots only — optical transceiver modules are ordered separately per required distance/connector type, not bundled with the switch.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES1000D-22T4GB series from its own datasheet: 22 × 10/100Base-T copper ports, 4 × 1000Base-X SFP slots, unmanaged, AC 220 V or DC 24 V / 48 V redundant input, max 6 W, IP40 DIN-rail housing.
Who it is for
- CCTV integrators aggregating a camera cluster — Up to 22 separately powered 100M cameras in one cabinet go back on a Gigabit SFP uplink, so the copper side never saturates the backbone; the switch has no PoE, so cameras need their own power.
- Building and campus access-control / alarm panels — 22 ports wire a whole floor of door controllers, alarm points or environmental sensors from one unit instead of daisy-chaining several small switches.
- Utilities, substations and pump stations — The -DCL (24 V) and -DCH (48 V) versions take dual redundant DC inputs with reverse-polarity and overload protection, and single-mode SFP optics reach 20 / 40 / 60 / 120 km back to the control centre.
- Factories and process plants — Many 100M PLCs, drives and HMIs in a line cabinet share a Gigabit fibre to the plant backbone; four SFP slots let one cabinet serve as a fibre hub for several neighbouring cabinets.
Where and how to install
- DIN rail in a closed cabinet — The body is 64 W × 174 H × 143 D mm and IP40, so plan a cabinet at least about 150 mm deep plus room for patch cords in front, and use a weatherproof enclosure outdoors. Wall-mount is optional.
- Choose and fit the SFP modules — Each slot takes a 1000Base-X SFP chosen for that link: multimode 0.5 / 2 km or single-mode 20 / 40 / 60 / 120 km, single- or dual-fibre. Single-fibre modules work in pairs with opposite wavelengths at the two ends. Keep dust plugs in empty slots and clean connectors before plugging in.
- Power: pick the version for the site — -AC takes 100–240 V AC on a single input; -DCL takes 12–36 V DC and -DCH 36–56 V DC, each on two redundant inputs of the 4-pin terminal. Feed the two DC inputs from separate supplies and fuse each one; at the listed max 6 W the draw is about 0.25 A at 24 V.
- Copper cabling and surge — Keep each copper run under 100 m; with 22 cables, use labelled cable management so ports can be traced later. Fit Ethernet surge protectors on any copper run that leaves the building, and bond the metal housing and rail to the cabinet earth.
- Temperature and condensation — Order the wide-temperature build for -40 to +75°C cabinets (standard build -10 to +60°C). Check that the SFP modules you fit are also rated for the cabinet temperature, and add a heater or breather where humidity could condense (rating 5–95% non-condensing).
Ports & uplink planning table
The ZJIES1000D-22T4GB is a 100M access switch with Gigabit fibre uplinks: 22 copper ports at 100 Mbps feed four 1 Gbps SFP slots. Even if every copper port ran flat out (2.2 Gbps), typical camera or PLC traffic is far lower, so one Gigabit uplink is usually enough and the other slots can link further cabinets in a line or star.

- Pick this model when one cabinet has 17–22 copper devices within 100 m and needs a Gigabit fibre back to the core.
- Pick ZJIES1000D-16T2S-DC instead when 16 copper ports and fixed 100M fibre are enough and you want no separate modules.
- Pick a managed ZJIES3000D model when the SFP uplinks must form a ring, or ZJIES1000D-P-8PGT4GB-DCH when cameras need PoE and four SFP uplinks.
Camera load assumes 8 Mbps per camera main stream; check your actual bitrate. SFP modules are ordered per link distance and are not part of the switch.
Industrial DIN-Rail Switch FAQ — ZJIES1000D-22T4GB
How many devices can the ZJIES1000D-22T4GB connect?
It offers up to 22 x 10/100Base-T copper ports for end devices plus 4 x 1000Base-X SFP gigabit uplink slots — the highest Fast Ethernet port count in the ZJIES1000D unmanaged line. Store-and-forward switching with an 8K MAC table and 4 Mbit buffer handles a full cabinet of field devices.
How far can the SFP fiber uplinks reach?
The 4 SFP slots accept multimode modules for 0.5 or 2 km, or single-mode modules for 20, 40, 60 or 120 km. Single- or dual-fiber and SC, ST or FC connector options are available, so you can match existing fiber plant between cabinets or sites.
What power inputs does it support?
Choose AC 220V (100–240V) single input, or DC 24V (12–36V) / DC 48V (36–56V) with redundant dual input on a 4-pin terminal. Reverse-polarity and overload protection are built in, and the switch itself draws a maximum of only 6 W.
Does it need any configuration before use?
No. It is an unmanaged plug-and-play switch — connect power and cables and it forwards traffic immediately. There is no software, console or web interface to set up, which keeps commissioning simple for field technicians. LED indicators show power, copper link and fiber link status.
Can it survive outdoor cabinet temperatures?
Yes. The standard version operates from -10 to +60°C and the wide-temperature version from -40 to +75°C, with storage from -40 to +85°C and 5–95% non-condensing humidity. The IP40 metal enclosure, EN61000-4 Level 3 EMS immunity and 320,000-hour MTBF suit roadside and plant cabinets.
How is the ZJIES1000D-22T4GB installed?
It mounts on a standard DIN rail by default, with wall mounting available as an option. The compact metal housing measures 64 x 174 x 143 mm, so it fits alongside PSUs and breakers in the same cabinet. It carries CE and FCC EMC approvals and a 5-year warranty.
Can I connect two SFP uplinks of the ZJIES1000D-22T4GB to the core for redundancy?
No. The switch is unmanaged, with no RSTP, ERPS ring or link aggregation listed, so two paths to the same core make a loop and a broadcast storm. Use one SFP as the uplink and the others to feed separate downstream cabinets in a line or star. If you need a backup path that takes over automatically, use a managed ZJIES3000D model and confirm the ring protocol with us.
Which SFP modules work in the ZJIES1000D-22T4GB, and can I use another brand?
The slots are 1000Base-X (IEEE 802.3z), so they need 1.25 Gbps Gigabit SFP modules: multimode 0.5 / 2 km or single-mode 20 / 40 / 60 / 120 km, single- or dual-fibre. 10G SFP+ modules will not work, and 100M SFP modules are not listed. Third-party module compatibility is not stated on the datasheet, so the safest path is to order the modules with the switch or confirm the brand and part number with us first.
Will 22 IP cameras on the ZJIES1000D-22T4GB overload the Gigabit uplink?
No. At an assumed 8 Mbps main stream per camera, 22 cameras send about 176 Mbps, roughly 18% of one 1 Gbps SFP uplink, leaving room for sub-streams and live viewing. The limit you hit first is per camera: each copper port is 100 Mbps, which is far above a normal camera stream. If several of these switches are chained over fibre, add up all cameras behind the last uplink.
Can I plug my NVR or a Gigabit server into a copper port of the ZJIES1000D-22T4GB?
It will work, but only at 100 Mbps, because all 22 copper ports are 10/100Base-T; with an assumed 8 Mbps per camera that caps one NVR port at roughly 10 cameras with headroom. For the full camera count, put the NVR on a Gigabit switch at the other end of the SFP uplink, or ask us whether a copper (RJ45) Gigabit SFP is supported in these slots, since none is listed.
Can the ZJIES1000D-22T4GB power cameras or access points over PoE?
No. None of the 22 copper ports has PoE output, and the whole switch is rated at max 6 W. Power the devices locally or with injectors, or choose a PoE model with SFP uplinks such as ZJIES1000D-P-8PGT4GB-DCH.
What power connector does the ZJIES1000D-22T4GB Series have, and do I need to confirm it before ordering?
Yes, please confirm the power connector with us before ordering. For Zhongxin Shutong products the power input type and connector can differ between versions and batches, so tell us your supply (AC or DC and the voltage), how you will wire it in the cabinet and your country's plug standard, and we confirm the exact connector and supply version of the ZJIES1000D-22T4GB Series for your order.
