3.2 Terminal arrangement
Notation for terminal arrangement is as follows.
C: Common
NO: Normal open
+, -: There is polarity for wiring.
A, B, b: There is designation for wiring.
CT: Current transformer input (no polarity)
DI: Digital input
RTD: Resistance temperature detector input
TC: Thermocouple input
I: Current input
V: Voltage input (excluding 0 - 10 mV)
* Parameters can be used for changing input types. (Multi-input)
* “NO” and “C” for outputs are for the equipment model with relay contact output. “+” and “-” for
other than the equipment model with relay contact output.
* Terminal block is not provided in case the model selection is not made at the product model.
