TM54F design

Terminal Module TM54F is a terminal expansion module for snap-on rail mounting to DIN
EN 60715. The TM54F features fail-safe digital I/O for controlling the Safety Integrated
Extended Functions.
Each Control Unit can be assigned only one TM54F which is connected via DRIVE-CLiQ.
NOTICE
The TM54F may not be interconnected in series with the Motor Modules and must be
operated on a separate DRIVE-CLiQ line (separate port on the Control Unit). Other
Terminal and Sensor Modules can be connected to this DRIVE-CLiQ line.
TM54F features the following terminals:

Sensors: Fail-safe devices for command operations and status logging (e.g. Emergency

Stop pushbuttons, safety door locks, position switches, and light arrays / light curtains).
Dynamic response: The sensor power supply is cycled on and off by the TM54F when the

forced dormant error detection is active for the sensors, cable routing, and the evaluation
electronics.
The TM54F provides 4 fail-safe digital outputs and 10 fail-safe digital inputs. A fail-safe
digital output consists of a 24 V DC switching output, an output switching to ground and a
digital input for reading back the switching state. A fail-safe digital input consists of two digital
inputs.
Note
You have the following options of acknowledging TM54F faults after troubleshooting:
• POWER ON
• Falling edge in signal "Internal Event ACK" with subsequent alarm acknowledgement on
