4-20 mA Input Alarm Trips with Loop Supply 

API 1005 G, API 1025 G

Applications

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.
