Terminal Module TM54F 
9.1.1
 
The TM54F Terminal Module is a terminal expansion module for snapping onto a mounting 
rail according to EN 60715. The TM54F offers safe digital inputs and outputs for controlling 
SINAMICS Safety Integrated functions.  
The TM54F must be directly connected to the PPU of SINUMERIK 828D via DRIVE-CLiQ. In 
so doing, the topology rules (Page 121) must be observed. 
TM54F features the following interfaces:

 power supply, no dynamization 
Digital inputs for testing the F-DO at test stop 
  Sensors: Fail-safe devices to issue commands and sense - for example, Emergency Stop buttons 
and safety locks, position switches and light arrays/light curtains. 
  Forced checking procedure: The sensor power supply is cycled on and off by the TM54F when the 
forced checking procedure is active for the sensors, cable routing, and the evaluation electronics. 
The TM54F has 10 fail-safe digital inputs and 4 fail-safe digital outputs. 
A fail-safe digital input comprises: 
●  2 digital inputs 
A fail-safe digital output comprises: 
●  Output switching to 24 V 
●  Output switching to ground 
●  Digital input to check the switching state
