With AS-Interface enclosures, command devices of the SIGNUM 3SB3 installed in a distributed configuration can be quickly con- nected to AS-Interface.

The enclosures without EMERGENCY STOP feature one 4I/4O

application module; an F adapter is mounted on EMERGENCY 6 STOP enclosures.

The contact blocks and lampholders of the command devices as well as the AS-Interface slave are soldered onto a carrier circuit board and screwed onto the command device.

In the case of EMERGENCY STOP enclosures, two normally closed contact blocks are mounted in the enclosure which are wired to the F adapter.

Addressing is via the AS-Interface connections or via the built-in addressing socket. An external supply voltage does not have to be connected.
