The 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 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.

Sink/Source Input and Loop Supply

For maximum versatility, a current input can be selectively wired for sinking or sourcing. This allows the API 1080 G to work with powered or unpowered mA inputs. An unregulated 18 VDC loop excitation supply can be used to power passive input devices eliminating the need for an additional DC loop supply.

LoopTracker and Alarm Status LEDs

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

Output Test / Unlatch

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.
