Description
The APD 1200 series accepts a thermocouple input and pro-
vide a visual alarm indication and alarm relay contact outputs.
The input type, range, and alarm types are factory configured.
The input can be factory configured for most thermocouple
types.
Front-accessible potentiometers are used to adjust alarm trip
and reset point(s).
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 bicolor alarm status LED(s) visually indicate
alarm status. These LED(s) provide a quick visual picture of
your process at all times.
Output Test / Unlatch
API's exclusive Output Test button can be used to verify the
alarm and system operation and also provides the additional
function of unlatching the alarm when the latching option has
been ordered.
The output test button greatly aids in saving time during initial
startup and/or troubleshooting.
