Absolute Process Instruments API 1420G Alarm Relay

The Absolute Process Instruments API 1420G Alarm Relay is a dual RTD-input alarm module that provides two independent setpoints with two SPDT relay outputs for HI/LO temperature alarms. It accepts RTD inputs (2- or 3-wire RTD) with input isolation and factory-range operation, enabling reliable temperature monitoring of motors and processes. Power is supplied from 85-265 VAC or 60-300 VDC, and the relays can drive external signals or interlock equipment; API documents motor bearing temperature alarms and shutdowns as a typical use case. With two independent setpoints and dual relays, the API 1420G is suited for motor protection, pump safety, and RTD-based temperature monitoring in industrial environments.
