to the TeSys™ island Functional Safety Guide, 8536IB1904.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.

A SIL* interface module (SIM), associated with one or several SIL starters, allows the design of Stop functions according to EN/IEC 60204-1:
-
Stop Category 0: immediate machine power disconnection
-
Stop Category 1: electrical power is maintained on the machine actuators until the stop process fully ends (absence of motion)
The reference number is TPRSM001.
The following are the main functions of the SIM:
-
Interface with an external interlocking device
-
Command the stop function of its SIL group of SIL starters
Several SIL groups of SIL starters can be set up on the TeSys island . Each SIL group is delimited by a SIM on the right side (or the top side if vertically mounted).
The SIM is connected upstream:
-
To the 24 Vdc source
-
To an interlock (for example, a Preventa™ XPS-AC module)
The SIM communicates with the bus coupler, sending operational data.
The Stop function is achieved by electromechanical means without any digital communication or bus coupler involvement.
