The 8DI Expansion Module is designed for building automation systems, featuring 8 digital inputs for pulse counting. It offers user-friendly configuration and includes status LEDs for all inputs, outputs, and communication. The module connects via RS-485 as a Modbus RTU slave, with an option for IP connection for Modbus TCP. Configuration of slave ID and baud-rate is easily managed using DIP switches.
