Inputs
Figure 6
RS-485 wiring from the EC-BOS to one or more IO-R-34 modules uses a "daisy-chain" connection.
Connect RS-485 shield wire to ground at one end only
Add up to 4 IO-R-16
modules per IO-R-34
Inputs
Each of the 16 universal inputs (UI) can support any one of the following:
Type-3 10K ohm
Thermistor
•
Resistive 0-100K ohms
•
•
0–10 Vdc
4–20 mA
•
Binary Input
•
Thermistor
The 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. 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 NRIO
Driver Guide for details.
