The APD 1420 accept an RTD temperature 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 10 Î© to 2000 Î© RTDs. Front-accessible potentiometers are used to adjust alarm setpoint and deadband.

LoopTracker and Alarm Status LEDs

API exclusive features include a LoopTracker LED that varies in intensity with changes in the process input signal. A two 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 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. This feature can be remotely operated. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
