2 Product description
2.1 Ordering code
This operating instructions manual applies to the following types:
SRB 207AN/1-230V
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefo-
re the compliance with the Machinery Directive is maintained.
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 module for integration in safety circuits is desig-
ned for fitting in control cabinets. It is 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 module has a multichannel structure. It includes
safety relays with monitored positive action contacts. The NO contacts
of the relays, which are wired in series, build the enabling contacts.
6 signalling outputs signal the position of the corresponding safety
guard.
