The Distributed I/O Module (ET 200M) consists of an interface module from Siemens and permits to connect analog I/O's using HART communication protocol to a Siemens PLC through PROFINET communication. This I/O module features eight 4-20 mA HART analog inputs and eight 4-20 mA HART analog outputs.

All the I/O'S can be hardwired to both banana jacks and terminal blocks on the module front panel. Banana jacks provide an easy and fast way to wire a setup, while terminal blocks allow students to wire their setup in a way much closer to what is commonly found in the industry.

This module has six switches that the instructor can use to insert faults.
