tons and safety locks, position switches and light arrays/light curtains.
Dynamic response: The sensor power supply is switched on and off by the TM54F when the
2)
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, a ground switching output, and a digital
input for checking the switching state. A fail-safe digital input comprises two digital inputs.
Note
Rated values of the F-DO
The rated values of the F-DO meet the requirements of IEC 61131-2 for digital DC outputs
with 0.5 A rated current.
The operating ranges of the F-DI meet the requirements of IEC 61131-2 for Type 1 digital
inputs.
Note
Shielding cables
Please note that the F-DIs must take the form of shielded cables if they are > 98 ft (30 m) in
length.
Note
Safety Integrated Function Manual
Detailed and comprehensive instructions and information for the Safety Integrated functions
can be found in the associated Function Manual. This manual is available as additional
documentation on the customer DVD supplied with the device.
