Description
The APD 14x1 series accepts an RTD or thermistor tempera-
ture input and provide a visual alarm indication and alarm
relay contact outputs.
The input type, range, and alarm types are factory configured.
The input can be configured for most RTDs or thermistors.
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 (two on the APD 1420)
visually indicate alarm status.
These LEDs 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.
non-latching, normal acting
non-latching, normal acting
IBA APD 1421 with inverse band alarm. Alarms trip if signal
is between LO and HI trip points.
HT Latching alarm with push button reset
HP Latching alarm with power-off reset. Module power
must be turned off to reset alarms
R Reverse-acting alarms. Relay coils energized in an alarm
condition. No alarm condition with module power off.
