Overview

The ZJTS804 is an industrial serial device server that supports up to 4 RS-232/485 serial ports in flexible combinations, bridging legacy serial equipment to 10/100M Ethernet networks with remote WEB-browser configuration. It is powered by DC5V (5–24V wide range, via optional 220V-to-5V adapter) or AC220V (85–264VAC/77–300VDC), drawing a maximum of 4 W with reverse-polarity and overload protection, and is available in a standard -10~60°C or wide-temperature -40~75°C version. Housed in a compact IP40 metal enclosure for desktop or wall-mount installation, it carries a 5-year warranty.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

Legacy Serial Equipment onto the NetworkUp to 4 RS-232/485 serial ports in flexible combination bridge legacy instruments, PLCs, and meters onto a 10/100M Ethernet network for remote access.

PLC & Automation Cell IntegrationBuilt-in Modbus TCP/IP support alongside DHCP/Telnet/TCP/UDP/ICMP/ARP lets PLCs and SCADA systems poll serial field devices directly over standard Ethernet.

Desktop Plug-and-Play DeploymentCompact 30×106×160 mm metal desktop/wall-mount enclosure needs no rack or cabinet — connect power and Ethernet and the unit is online.

Wide-Temperature Outdoor / Unheated CabinetThe optional wide-temperature version operates from -40 to 75°C (storage to -40~85°C), suited to unheated outdoor cabinets facing cold winters and hot summers.

Mid-Scale Multi-Device Serial Consolidation4 independent RS-232/485 ports — double the port count of the 2-port ZJTS802 — let one unit consolidate several serial instruments, PLCs, or meters at a single network drop, right-sized between single-device and 8/16-port rack units.

Long-Run RS-485 Field Wiring Surge ImmunityBuilt-in 15KV ESD protection on all 4 serial ports, plus EN61000-4 series Level 3 EMC immunity, guards against lightning-induced surges and EMI picked up along long RS-485 field cable runs to remote instruments.

Not a good fit if:

Single 10/100M Ethernet uplink port only — not a multi-port network switch; use a separate switch for LAN fan-out.
Single, non-redundant DC5V or AC220V power input per SKU — no dual/redundant power option in this datasheet.
IP40 enclosure only — needs a cabinet or additional protection for direct outdoor rain/dust exposure.
