Failsafe:

  • Normally energized (failsafe), or
  • Normally de-energized (non-fail-safe)


Latching:

  • Latching, or
  • Non-latching


Time Delay:

0 to 25.5 seconds in 100msec increments


Voting Logic:

Per relay, defined as "A out of B" where "B" is up to 16 alarms from any measurement module(s) on the bus and "A" is from 1 to "B"


Reset:

  • Local reset switch on top of module
  • Remote reset switch wired to terminal base
  • Digital reset command via serial or DeviceNet interface


Activation On:

  • Alarm Status
    • Normal
    • Alert
    • Danger
    • Disarm
  • Transducer Fault
  • Module Fault
  • Tachometer Fault
