Model AP1000-1024 DC Input, Limit Alarm

Brand: Eurotherm
Request Information
Favorite

The Action Pak 1000 Series Limit Alarms are compact, electronic plug-in modules that receive a DC input (Input range is factory-set) and compare that input to a field adjustable setpoint.

Limit alarms are setpoint controllers that regulate industrial processes or detect process problems.
Features
  • Provides relay contact closure(s) at a preset DC input level
  • Exclusive "Dynamic Deadband" prevents false trips
  • "Failsafe" operation available
  • DC signal alarm/control applications
  • Voltage/current input protection
  • Single, latching or dual setpoint
  • AC Line powered (DC optional)
