Feature: 1. Communication Protocol: The communication protocol adopts standard for Modbus TCP protocol, for Modbus RTU over TCP protocol and MQTT protocol. 2. Reliable Performance: Support 8 channel digital input (DIN), 8 channel digital output (DO), 8 channel analog input (AIN). 1 port RS485 communication interface, supporting the standard for Modbus RTU protocol for expansion. 3. Effective Protection: Wide working voltage DC9‑36V, and anti reverse connecting protective function. Equipped with LED indication of working state, with reset button and convenient to field installation and debugging. 4. Strong Construction: Adopt metal shell, protection level IP30, and the metal housing and system are safely separated, especially suitable for industrial control field applications. 5. Easy to Operate. It can be managed and configured through LAN configuration software, easy to operate and maintain.
