Safe PLC Interface Option MCB 108
The MCB 108 option module is a galvanically isolated
slot B.
What is the MCB108 Option:
It is designed to be built in between the Safe dual pole(plus/minus) on the Safe PLC and the Safe Stop input
on FC302. The Safe PLC interface allows the safe output on the Safe PLC, to maintain the test pulses on the
plus and minus output without impacting the sensor signal to safe stop T37.
Can be used in combination with safety devices to satisfy the requirement of IEC61800-5-2 SIL 2,
ISO13849-1 PL d, and Category 3 (EN954-1) for Safe Torque Off (STO)

Following precautions have to be observed:
- The FC 302 with MCB 108 (including the connections
between X31/9 and Terminal 37) must be placed inside
an IP54 enclosure.
- Safe Stop activation (i.e. removal of 24 V DC voltage
supply to terminal 37 by removing voltage to dual pole
input of MCB 108) does not provide electrical safety.
- The safety device connected to the dual pole input op
MCB 108 must itself fulfill the requirements of EN 954-1
Cat. 3 ISO13849-1 P Ld for interrupting the voltage/
current to MCB 108. This is also valid for the connections
between MCB 108 and the safety device. You must read
and follow the instructions for the safety device in order
to connect it properly to MCB 108.
