Action PAK® AP1080 & AP1090 DC Input, Field Configurable Limit Alarms

Provides Relay Contact Closures at a Preset DC Input Level.

 

Features:

  • Field Configurable Input Ranges for DC Voltage and Current
  • Exclusive "Dynamic Deadband" Prevents False Trips
  • Setpoints Programmable HI or LO
  • Selectable Failsafe/Latching Operation
  • Selectable 120/240VAC Input Power (9 to 30 VDC Available)

AP1080 (Single Trip, DPDT, 5A)
AP1090 (Single/Dual Trip, 2 SPDT, 5A)

Description
Action Pak models AP1080 single setpoint and AP1090 dual setpoint limit alarms offer flexible, wide-ranging DC input capability. Voltage spans from 10mV to 200 volts and current spans from 1mA to 100mA can be field configured. Bipolar inputs are also accepted. Both models offer configurable latching, failsafe and HI/ LO operation. The AP1080 and AP1090 also include 0.25%-50% adjustable deadbands and selectable 120/240VAC input power.

Operation
The field configurable AP1080 and AP1090 limit alarm setpoints can be configured for HI, LO, latching or failsafe trip operation. Non-latching HI and LO setpoints have respective HI and LO deadbands. In a tripped condition, the setpoint is exceeded and the appropriate red LED will illuminate. The trip will reset only when the process falls below the HI deadband or rises above the LO deadband (see figure 1). To reset a latched setpoint the signal must be in the safe region and the line power turned off for at least 5 seconds. For proper deadband operation, a HI setpoint must always be set above a LO setpoint.

In failsafe operation, the relay is energized when the process is below the HI setpoint or above the LO setpoint (opposite for non- failsafe). In the failsafe mode, the relays go to the tripped condition when the power fails.
