1) 
Sensors: Fail-safe devices for commanding and detecting, such as emergency stop 
pushbuttons and safety locks as well as position switches and light arrays / light curtains.
2) 
Dynamic 
response: The sensor power supply is switched on and off during test stop for testing 
the sensors, the cable routing, and the evaluation electronics of TM54F.
The TM54F has 4 fail-safe digital outputs and 10 fail-safe digital inputs. A fail-safe digital output 
consists of a P/M-switching output as well as a digital input for reading back the switching 
state. A fail-safe digital input is made up of two digital inputs.
 
 
NOTICE
Overheating if ventilation clearances are too small
Insufficient ventilation clearances result in overheating and therefore in more failures and a 
shortened life of the component.
Maintain 50 mm ventilation clearances above and below the component.

Features of TM15 and TM17 High Feature      
The TM15 and TM17 High Feature Terminal Modules are used to implement inputs of 
measuring inputs and outputs of output cams for SIMOTION D. In addition, these Terminal 
Modules provide drive-related digital I/Os with short signal delay times. TM15 and TM17 High 
Feature are connected via DRIVE‑CLiQ.   
TM15
Each of the 24 electrically isolated digital I/Os can be parameterized channel-by-channel as 
a digital input (DI), digital output (DO), a measuring input input, or an output cam output.
TM15 DI/DO
Each of the 24 isolated digital I/Os can be configured on a channel-specific basis as a digital 
input (DI) or digital output (DO). The digital I/Os can be interconnected using BICO technology 
and thus used from the drive side as well. Unlike the TM15, measuring input inputs and cam 
outputs are not available with the TM15 DI/DO. 
Note: The module hardware for TM15 and TM15 DI/DO is identical. A distinction is only made 
by the addition of the component in the SIMOTION SCOUT Project Navigator using "Inserting 
input/output component."
