Fail-safe inputs and outputs
TM54F Terminal Module (option K87)
The TM54F Terminal Module (
option K87
) is a dual-processor
I/O interface with 4 fail-safe digital outputs and 10 fail-safe
digital inputs for using Safety Integrated functions of the
SINAMICS S150 drive via external actuators and sensors.
All of the available safety functions integrated in the drive
can be controlled via the fail-safe digital inputs of the TM54F
Terminal Module.
The fail-safe digital outputs and inputs have two channels
with an internal crosswise data comparison via the two
processors. A fail-safe digital output consists of one
P-switching and one M-switching output as well as one dig-
ital input to read back the switching state. A fail-safe digital
input consists of two digital inputs.
Safety sensors can be connected over two switchable 24 V
sensor supplies and evaluated via the fail-safe digital inputs.
The switchable 24 V sensor supply ensures that the fail-safe
digital inputs can be dynamized to detect dormant errors
(this dynamization is used to check the shutdown paths).
A non-switchable 24 V sensor supply is additionally provided
by the TM54F Terminal Module for connecting safety sensors
that cannot be dynamized.
The TM54F Terminal Module is connected directly to a
Control Unit via DRIVE-CLiQ. Each Control Unit can only be
assigned to one TM54F Terminal Module.
Additional DRIVE-CLiQ nodes such as Sensor Modules and
Terminal Modules (however no additional TM54F Terminal
Module) can be operated on the TM54F Terminal Module.
The following are located on the TM54F Terminal Module:
• 4 fail-safe digital outputs
• 10 fail-safe digital inputs
• 4 LEDs, single color for indicating the status of the read
back channel of the fail-safe digital outputs
• 4 LEDs, dual-color for indicating the status of the fail-safe
digital outputs
• 20 LEDs, dual-color for indicating the status of the fail-safe
digital inputs
• 3 LEDs, single color for indicating the status of the 24 V
sensor supplies
• 2 connections for 24 V sensor supply, switchable
• 1 connection for 24 V sensor supply, non-switchable
The signal cable shield can be connected to the TM54F
Terminal Module via a shield connection terminal, e.g.
Phoenix Contact type SK8 or Weidmüller type KLBÜ CO 1.
The shield connection terminal must not be used for
strain relief.
The status of the TM54F Terminal Module is indicated via a
multicolor LED.
Pins for connector coding are included in the TM54F
Terminal Module scope of delivery.
