API 1025 G
Description
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
loop-powered transmitter or other passive input device. Heavy
duty relay contacts allow directl control of high capacity loads.
The API 1005 G provides a single setpoint adjustment and
DPDT relay contacts. The alarm output can be factory config-
ured for HI or LO operation, non-latching or latching, normal
or reverse acting. Top-accessible potentiometers are used to
adjust the alarm setpoint and deadband.
The API 1025 G contains two independent setpoints with two
SPDT relay contact outputs. The alarm output can be factory
configured for HI/HI, HI/LO, LO/HI or LO/LO operation, normal
acting or reverse acting. 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 red/green bi-color alarm status LED (two on the API 1025
G) visually indicate alarm status. These LEDs provide a quick
visual picture 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.
