Safe digital relay outputs (floating contacts)

The safety module has four safety relays each with two floating relay contacts (relay
outputs), which can be used as follows:
For two-channel assignment:
– Two two-channel relay outputs
For single-channel assignment:
– Four single-channel relay outputs

For the technical data for the safe relay outputs, please refer to page 11-4.
Protect the relay outputs against overcurrent with a suitable fuse. Fuses with an l

of less than 100 A s and a nominal current of less than or equal to 6 A are permitted.
WARNING: Loss of the safety function when using miniature circuit breakers
Miniature circuit breakers are not suitable for protection in the 230 V 50/60 Hz mains and
must not be used.
At 24 V DC, a 4 A miniature circuit breaker with characteristic C can be used, whereby the
maximum short-circuit current (IK) of 250 A must not be exceeded. Make sure that the
miniature circuit breaker trips in the event of a short circuit for your DC application. This
depends on the power supply unit used.
