The Schneider Electric TM172ASCTB07 is a screw terminal block accessory designed for use with Modicon M171/M172/M173 logic controllers, specifically to support modules with 7 I/O points. It provides a removable screw terminal interface that facilitates secure and organized wiring of the controller’s digital and analog input/output field wiring, power supply, and communication lines (such as Modbus RS‑485 or CAN). Its green housing is characteristic of the Modicon M17x accessory range.
