Single Channel Speed Monitor for increased safety requirements up to SIL2

  • Single channel monitor E16521D with sensor monitoring and self-test function with plausibility check
  • 1 Analog Output 0/4…20 mA
  • 4 Setpoint Alarms, 2 as SPDT contacts and 2 as opto-relays
  • Universal Inputs, also for magnet inductive sensors (MPUs)
  • Square wave pulse output
  • RS232 Data Interface
  • Two monitors, suitably configured with their setpoint contacts linked together, may provide a protection system with 1oo2 or 2oo2 redundancy
  • Increased safety with 1oo2 architecture
  • Maximum availability with 2oo2 architecture
  • SIL2 / IEC 61508:2010 compliant
