2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond
to the standard version.
2.3 Destination and use
The safety-monitoring modules for integration in safety circuits are
designed for fitting in control cabinets. They are used for the safe
evaluation of the signals of positive break position switches for safety
functions or magnetic safety sensors on sliding, hinged and removable
safety guards as well as emergency stop control devices.
Design
The safety-monitoring modules have a dual-channel structure. They
include two safety relays with monitored positive action contacts. The
NO contacts of the relays, which are wired in series, build the enabling
contacts.
