Chapter 12 Thermocouple Input Option Module (XBO-TC02A)
(2) Terminal array
Terminal array of thermocouple input module is as follows.
(3) Wiring example
Thermocouple can be connected with module directly. If point where temperature is measured is
far from the module, use the compensating cable to connect
(The compensating cables are different according to thermocouple type. For more information
about the compensating cable, contact the producer of thermocouple.)
1)
In case sensor and compensating cable are shielded, shield connection is possible to PLC FG terminal.
2)
It is necessary to use extension terminal block of which material is kept at uniform temperature in order
to reduce error.
3)
Compensating cable should use the same type of sensor, which was used for measuring.
Purpose
Channel 0 thermocouple input
Channel 1 thermocouple input
