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.

All three configurations share the same port layout — 22 × 10/100Base-T copper + 4 × 1000Base-X SFP Gigabit uplink slots (single-/multi-mode, SC/ST/FC connector, single-/dual-fiber selectable; multimode 0.5/2 km, single-mode 20/40/60/120 km). They differ only in power input: -AC = AC 220V (100–240V) single input; -DCL = DC 24V (12–36V) redundant dual input; -DCH = DC 48V (36–56V) redundant dual input.
