The API 1005 G and API 1025 G are factory configured for a 4-20 mA current input and provides alarm contact outputs. The 4-20 mA input provides power to the input loop via a built-in 18 VDC loop power supply that can be used to power a looppowered transmitter or other passive input device. Heavy duty relay contacts allow direct control of high capacity loads.

The API 1025 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 process 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.
