Item #API 1020 G A230, API Plug-In Alarms

The API 1080 G and API 1090 G accept a DC voltage or current input and provide visual alarm indication and alarm relay contact outputs. Voltage and current input ranges can be field-configured via external rotary and slide switches. Offset ranges such as 1-5 VDC and 4-20 mADC are also included. Heavy-duty relay contacts allow the module to directly control high capacity loads. Top-accessible potentiometers are used to adjust the alarm setpoint from 0 to 100% and the deadband from 1 to 100%.

The API 1080 G provides a single setpoint adjustment of the two DPST relay contacts. The alarm output can be field configured for HI or LO operation, latching or non-latching, and normal or reverse acting. The deadband and alarm setpoint is adjustable.

The API 1090 G provides two setpoint adjustments of the two SPDT relay contacts. The alarm outputs can be configured in the field for HI/HI, LO/LO, HI/LO or LO/HI operation, latching or non-latching, and normal or reverse acting. Deadband and alarm setpoints are independently adjustable for each alarm.
