The TP3 connection module is used for a 3-wire connection with 8 channels and potential connection. It features push-in terminals without LED for signalling. The module serves as the interface between the connecting cables of the peripherals and the SIMATIC S7. It is mounted on the DIN rail and is specifically designed for the task at hand. The TP3 connection module is part of the SIMATIC TOP connect system, which offers fast and secure system cabling. By using connection modules from SIMATIC TOP connect, wiring costs are reduced and potential errors in cabling are minimized. Sensors and actuators from the peripherals are connected to the SIMATIC S7-1500 via cable and front plug-in module.
