Features: Class | Gr. D, C & D; Class || Gr. E, F & G Small Size - Mounts directly on Conduit Single or Dual Channel Operating Modes 3 Form "C" Contracts Easily Adjustable Setpoint and Deadband High-Trip or Low-Trip Operation Normally Energized or De-Energized Relay Mode Easy Field Calibration (Typ. calibration time < 2 min. using handheld meter only) Microprocessor Controlled for High Accuracy Power: 24 VDC, 60 mA High Noise Rejection

Function:
The XUA-XD Alarm Trip is a microprocessor based instrument. It has single or dual channel mode of operation. It can be configured as a high trip or a low trip (selectable by push-on pins inside the instrument). the relays can be configured as a normally-energized or normally de-energized. The output is 3 SPDT (form "C") contracts rated at 0.4 Amps, at 125 VAC. The 3rd relay is used as an input fail (below 2mA) in the case of 4-20mA inputs.

The deadband can be adjusted from 0-100%. The delay is delectable as 0 or 5 minutes ON delay.

Specifications: X=1: 1 to 5 mA (Zin = 1K Ohm) X=2: 4 to 20 mA (Zin = 250 Ohm) X=3: 0 to 1 mA (Zin = 5k Ohm) X=4: 10 to 50 mA (Zin 100 Ohm) X=5: 1 to 5 VDC (Zin = 1Meg Ohm) X=6: 0 to 10 VDC (Zin = 1Meg. Ohm) X=7 Special Input
