Overview

The ZJTS802 series is an industrial serial device server (serial-to-Ethernet gateway) that connects up to 2 RS-232/485 serial ports to a 10/100M Ethernet network, letting legacy serial equipment go online without replacement. It mounts on a desktop or wall, and is powered by DC5V (via an optional 220V-to-5V adapter, 5-24VDC input range) or by AC220V through a 3-pin terminal (85-264VAC/77-300VDC), with reverse-polarity and overload protection built in. An optional wide-temperature version extends operation to -40~75°C, and the compact IP40 metal enclosure with strong EMC immunity suits industrial environments.

Is This the Right Fit?

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

Bring Legacy Serial Equipment Online2 × RS-232/485 serial ports let you convert legacy serial-only PLCs, meters, and sensors to 10/100M Ethernet (legacy serial to IP) without replacing the device.

PLC & Automation Cell NetworkingBuilt-in Modbus TCP/IP protocol support lets both serial ports bridge PLC/automation controllers straight into the plant Ethernet.

Desktop Plug-and-Play DeploymentCompact 23(H)×112(D)×77(W) mm desktop or wall-mount enclosure needs no rack or DIN-rail — place it next to the device and connect.

Outdoor / Extreme-Temperature CabinetsAn optional wide-temperature version operates from -40 to 75°C for unheated cabinets and outdoor enclosures.

Smallest Model in the ZJTS Family — Single-Point RetrofitAt 23×112×77mm this is the most compact model in the ZJTS802/804/804D/808/816/832 line — sized for a single 2-port serial-to-Ethernet retrofit at one desk or panel.

ESD & Surge-Prone Industrial SitesAll serial ports carry built-in 15KV ESD surge protection inside an IP40 metal enclosure, guarding against static discharge from cabling and handling.

Not a good fit if:

Only 2 serial ports per unit — for higher port-count serial fleets, see the larger ZJTS804/804D/808/816/832 models in this series.
IP40 enclosure only — not rated for outdoor direct-exposure or washdown environments; use an external cabinet outdoors.
Single 10/100M Ethernet uplink with no VLAN/ring-network switching features — this is a serial gateway, not a managed switch.

All three ZJTS802 variants share identical performance, power, and physical specifications per the datasheet; they differ only in serial port protocol — RS-232 (-S-232), RS-485 (-S-485), or RS-232/485 combo (-M).
