Fail-safe standstill monitors

AZR 31 S1 and FWS range standstill monitors serve for fail-safe registration of machine standstill and control of safety solenoid interlocks on sliding, hinged or removable guard doors. Depending on the external circuits arrangements, the protection system can be secured up to the requirements of Control Category 4 to EN ISO 13849-1 in combination with an AES or AZR range safety monitoring module.
