Safety Bus coupler
A 2-pin plug-in terminal block with screw flange is used to connect the system supply to the
bus coupler. Since the bus coupler supplies power to both the E-bus and the logic circuits of
the Safety controller c250-S and the Safety I/O-modules, its power consumption depends on
the Safety controller c250-S and the number of Safety I/O-modules connected.
Power to the I/O module outputs is supplied separately
