Absolute Process Instruments API 1420 G _ RTD input dual alarm

Features with all optional accessories:

  • Automatic Leadwire Compensation
  • Field Adjustable Setpoints
  • Plug-In Design for Fast Installation
  • Input LoopTracker® and Alarm Status LEDs
  • Alarm Test Button

Applications:

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

The API 1420 G are factory configured for an RTD input and provide alarm contact outputs. Heavy duty relay contacts allow the module to directly control high capacity loads.

The API 1420 G contains two independent setpoints with two SPDT relay contact outputs. The normal acting alarm output can be factory configured for HI/HI, HI/LO, LO/HI or LO/LO operation. Top-accessible potentiometers are used to adjust each alarm setpoint. Deadband is fixed at 1% of span. Adjustable deadbands are optional.

LoopTracker and Alarm Status LEDs

API exclusive features include a LoopTracker LED that varies in intensity with changes in the RTD 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

API’s exclusive functional test button can be used to verify the alarm and system operation. Press the Test button to toggle the alarm relay(s) to the opposite state. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
