WEB/CP-202-XPR AND WEB/CP-602-XPR CONTROLLERS
15 95-7775—01
I/O WIRING
The WEB/CP-202-XPR and WEB/CP-602-XPR controllers have 16 on-board I/O points that include:
• Eight (8) Universal Inputs that support analog inputs (temperature, resistance, voltage, and current) and digital inputs (contact
closure, pulse count).
• Eight (8) Outputs that include 4 analog outputs (0 to 10 Vdc) and 4 relay (24 Vac/dc, 0.5A max.) digital outputs.
See Fig. 8. for location of I/O terminals.

Inputs
Each of the 8 universal inputs (UI) can support any one of the following:
• Thermistor Type-3 10K ohm (also see CAUTION on page 16)
• Resistive 0 to 100K ohms
• 0 to 10 Vdc
• 4 to 20 mA
• Binary Input (Contacts or Pulse)
Thermistor
Inputs support 10K Thermistor temperature sensors. Input accuracy is in the range of ±1% of span. By default, conversion is for
a standard Type 3 thermistor sensor, with a sensor range of -10 to 135°F (23.3 to 57.2°C). Using a conversion type of “Tabular
Thermistor,” you can specify a different thermistor response curve, by importing a thermistor curve .xml file. Currently, the kitIo
module contains an xml folder with thermistor curves for a various thermistor temperature sensors. You can also edit and export
(for reuse) customized thermistor curve xml files. See the NiagaraAX NRIO Guide for details.
Fig. 9 on page 16 shows the wiring diagram for a Thermistor sensor.
