Absolute Process Instruments API 1220 G _ Thermocouple input dual alarm

Features with all optional accessories:

  • Automatic Cold Junction Compensation
  • Field Adjustable Set and Reset
  • Plug-In Design for Fast Installation
  • Input LoopTracker® and Alarm Status LEDs
  • Alarm Test, Optional Reset Button

Applications:

  • Process Limit Backup Alarm
  • Temperature Alarm
  • Over, Under, Out-of-Range Alarm

The API 1220 G are factory configured for a thermocouple input and provide alarm contact outputs. Heavy duty relay contacts allow the module to directly control high capacity loads.

The API 1220 G contains two independent set and reset adjustments with two SPDT relay contact outputs. The alarm output can be factory configured for HI/HI, HI/LO, LO/HI or LO/ LO operation, normal acting or reverse acting. Top-accessible potentiometers are used to adjust each alarm trip and reset points.

LoopTracker and Alarm Status LEDs

API exclusive features include a LoopTracker LED that varies in intensity with changes in the thermocouple input signal. A two red/green bi-color alarm status LED visually indicate alarm status. These LEDs provide a quick visual picture of your process at all times.

Output Test/Reset

API’s exclusive functional test button can be used to verify the alarm and system operation. The output test button greatly aids in saving time during initial startup and/or troubleshooting. The HT latching option provides the additional function of unlatching the alarm when the reset button is pressed. The alarm will reset if the alarm condition not longer exists.
