The SDM-8I8O has 8 digital inputs with configurable timer/counter option and 8 high-power transistor outputs. Each channel can be individually configured in one of several modes.This module is connected to the RS485 bus with twisted-pair wire. Communication is via MODBUS RTU or MODBUS ASCII. The baud rate is configurable from 2400 to 115200. 

The module is designed for mounting on a DIN rail in accordance with DIN EN 5002. The module is equipped with a set of LEDs used to indicate the status of inputs and outputs useful for diagnostic purposes and helping to find errors.
