Overview

The EMS-200-150 is a compact industrial IoT gateway and environment monitoring host that connects RS-485 serial devices and digital-input sensors to a TCP/IP Ethernet network through 2 × RS-485 ports and 6 × DI channels. Compared with the full-featured EMS-200, this version omits the RS-232 port and DO relay outputs, keeping the same 32-bit processor, Modbus TCP/RTU/ASCII, SNMP MIB-II and Syslog support inside a smaller 180×44×96.5mm 1U rack-mount chassis. Powered by DC48V (36–56VDC input, 230mA@12V), its I/O is limited to 6 × DI digital inputs with no relay/DO output, making it suited to status-monitoring points rather than remote switching control.

Is This the Right Fit?

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

Server / Equipment Room Environment Monitoring6 × DI digital inputs plus 2 × RS-485 ports let a single 1U EMS-200-150 collect door/water/smoke alarm contacts and poll Modbus RTU sensors in the same equipment room, feeding readings to a Modbus TCP monitoring platform over Ethernet.

Unheated / Extreme-Temperature Cabinet SitesAn optional wide-temperature build extends operation from the standard -10~60°C to -40~+75°C, suiting unheated equipment rooms and outdoor cabinets exposed to seasonal extremes.

Pure Status Monitoring Without Control OutputsWith only 6 × DI digital inputs and no DO relay outputs, the EMS-200-150 is built for points that only need state acquisition (open/closed, alarm contacts) rather than remote on/off switching.

Space-Constrained Cabinet InstallationAt 180×44×96.5mm, the EMS-200-150 is noticeably smaller than the full-featured EMS-200 (240×44×110mm), freeing rack depth and width in tight cabinets.

Centralized Log Server IntegrationBuilt-in support for the Syslog standard logging protocol (alongside Modbus/SNMP/HTTP) — a capability this compact model adds beyond the base EMS-200 — lets it forward events directly to an existing centralized syslog server.

Two Independent RS-485 Monitoring LoopsThe 2 × RS-485 ports (terminal block, Data+/Data-) can each address a separate Modbus RTU device chain, letting one host poll two independent groups of serial sensors or meters at speeds from 110 to 460,800bps.

Not a good fit if:

No RS-232 port — only 2 × RS-485 ports are available, so RS-232-only serial devices cannot be connected directly.
No DO relay outputs — only 6 × DI digital inputs are provided, so remote switching/control of external circuits is not supported; monitoring only.
IP40 enclosure only — needs a rack cabinet or additional protection for direct outdoor rain/dust exposure.

This page covers the model requested as EMS-200-150. The datasheet order code is ZJEMS-200-150-DCH (chassis silkscreen: ZJEMS-150), denoting the DC48V-powered 2×RS-485 + 6×DI environment monitoring host. No other port or power variant is listed in this datasheet.

Industrial IoT Gateway FAQ — EMS-200-150

What devices can I connect to the EMS-200-150?

Two RS-485 serial ports on terminal blocks (110 to 460,800 bps) and six digital-input channels, all bridged to a 10/100 Mbps Ethernet port. Typical loads are meters, sensors and other Modbus RTU/ASCII field devices that need to reach a Modbus TCP master or monitoring platform.

How is the EMS-200-150 different from the EMS-200?

This version omits the RS-232 port and the DO relay outputs: you get 2 × RS-485 and 6 × DI only, in a smaller 180 × 44 × 96.5 mm 1U chassis. The 32-bit processor, Modbus TCP/RTU/ASCII, SNMP and Syslog support stay the same — pick it when relay output control is not required.

How is it powered on site?

It takes 48 V DC nominal with a wide 36–56 V DC input range and draws about 230 mA at 12 V. A 12 V / 30 W high-power DC output is also available to feed sensors or small field devices, saving a separate power supply in compact monitoring cabinets.

Is it protected enough for harsh equipment rooms?

Serial signals carry 15 kV ESD protection, all I/O ports use photoelectric and electromagnetic isolation, and the Ethernet port has built-in 1.5 kV electromagnetic protection. Standard units run -10 to +60 °C and the wide-temperature range covers -40 to +75 °C, in an IP40 metal enclosure rated 320,000 hours MTBF.

How do I configure and integrate it with my software?

Configure via web browser, Telnet or console, with Windows management software plus Real COM (Windows) and TTY (Unix/Linux) drivers for legacy serial applications. Protocol support covers Modbus, TCP/UDP, DHCP, Telnet, SNMP, HTTP and Syslog, fitting both SCADA polling and IT-style monitoring. Warranty is 5 years.
