Can I connect a thermocouple to the Zelio Logic Smart Relays?
Issue:
Customer would like to use a J type thermocouple input on the SR2 SR3 Zeliologic relays.
Product line:
Zelio Zeliologic smart relay SR2 SR3
Environment:
all
Cause:
Application
Resolution:
There is only one module that comes with a thermocouple input. The expansion module, from the SR3 series, is part number SR3XT43BD.
This allows one input for a PT100 thermocouple only. If they would like to use the SR2 series or not add the expansion module, add an interposing analog convertor to change the thermocouple signal to an analog signal of 0-10V, 0-20mA or 4-20mA input for the Zelio logic to work.
This uses analog in IJ, which is rated as -25 to +125C (-13 to +257F)
Maximum cable distance is 10m (32 feet)
