signal type... Description
Thermistor Precon type 2 (10 kOhm at 77°F). Input voltages should be from
0.489 Vdc to 3.825 Vdc for thermistors.
RTD
0–10 Vdc
4-20 mA
Dry contact A 5 Vdc wetting voltage detects contact position, resulting in a 0.5
mA maximum sense current when the contacts are closed.
0–20 mA The input impedance of the UC Open XP is approximately 1 MOhm.
