The APD 1090 accept a DC voltage or current input and provide visual alarm indication and alarm relay contact outputs. 15 voltage and 9 current input ranges can be field-configured via external rotary and slide switches. Offset ranges such as 1-5 VDC and 4-20 mADC are also included. Heavy-duty relay contacts allow the module to directly control high capacity loads. Front-accessible potentiometers are used to adjust the alarm setpoint from 0 to 100% and the deadband from 1 to 100%. The APD 1080 provides a single setpoint adjustment of the two DPST relay contacts. The alarm output can be field configured for HI or LO operation, latching or non-latching, and normal or reverse acting. The APD 1090 provides two setpoint adjustments of the two DPST relay contacts. The alarm outputs can be configured in the field for HI/HI, LO/LO, HI/LO or LO/HI operation, latching or non-latching, and normal or reverse acting. Deadband and alarm setpoints are independently adjustable for each alarm.

Sink/Source Input and Loop Supply

For maximum versatility, a current input can be selectively wired for sinking or sourcing. This allows the APD 1090 to work with powered or unpowered mA inputs. A regulated 15 VDC loop excitation supply can be used to power passive input devices eliminating the need for an additional DC loop supply.

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 status 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 mode has been selected. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
