The MOD-4DO module is an innovative device that provides a simple and inexpensive extension of the amount of input and output lines in popular PLC.

The module MOD-4DO communicates with all commercially available PLCs and other devices that support popular Modbus Master protocol.

The MOD-4DO module has 4 digital outputs. All outputs are isolated from the logic by optocouplers.

This module is connected to the RS485 bus with twisted-pair wire. Communication is via MODBUS RTU or MODBUS ASCII. The use of 32-bit ARM core processor provides fast processing and quick communication. 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.

Module configuration is done via USB by using a dedicated computer program - Modbus Configurator (free). You can also change the parameters using the MODBUS protocol.

Available accessories:

Programming cable 1,0m: mini USB-1
Programming cable 1,8m: mini USB-2
