Issue

Which signal types can be connected to a UI on a Xenta I/O Modules?

Product Line

TAC Vista

Environment

Xenta 451A/452A, 421A/422A

Cause

UI is short for universal input, which means that these inputs are compatible with many different input types.

Resolution

Supported input signal types are:

  1. Thermistor: 1.8 KΩ at 25 °C or 10KΩ at 25 °C;
  2. Voltage: 0 to 10VDC;
  3. Current: 0 to 20mA;
  4. Digital Input.
