ASM2E

Safety Monitor


ASM2E - Safety Monitor
CE TÜV Rheinland UL listed CSA AS-Interface - Safety at work

The ASM2E Safety Monitor has all the functionalities and features of the ASM1E Safety Monitor. Several safety-related actuators, such as drives or valve modules, can be monitored and safely switched simultaneously with just one ASM2E Safety Monitor.


Special features
  • Safety-related control of safe AS-i actuators with same safe AS-i address

  • Higher level start and emergency STOP functions with safety-related coupling of adjacent AS-i networks

  • Help signals for start/restart interlock status

  • AS-i actuator error restart

  • Additionally: All ASM1E Safety Monitor functions and features are provided
