DC Input Alarm Trips with Transmitter and Loop Supply
API 1040 G
Applications
Description
The API 1040 G alarm/transmitter accepts a DC voltage or
current input and provides both transmitter and alarm func-
tions in one unit.
The API 1040 G also provides a linearly-transferred DC voltage
or current output. The API 1040 G transmitter output is useful
for signal scaling, or translation from current to voltage or vice-
versa in applications that do not require isolation.
This module includes an unregulated 18 VDC loop excitation
supply that can be used to power an external loop-powered
transmitter or other passive input device eliminating the need
for an additional DC loop supply.
The API 1040 G provides a visual alarm indication and an SPDT
alarm relay output when the input exceeds a high alarm trip
point or falls below a low alarm trip point.
The alarm output can be factory configured for HI or LO opera-
tion, non-latching or latching, normal or reverse acting. Top-
accessible potentiometers are used to adjust the alarm setpoint
and deadband. Heavy-duty relay contacts allow the module to
directly control high capacity loads.
Setpoint Retransmission Option
The setpoint retransmission (SPR) option provides an analog
0-1 VDC signal corresponding to the setpoint potentiometer
adjustment. This allows remote monitoring of the alarm setting.
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 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.
