Connecting a Cold Junction Sensor to the 1756-IT6I Module
You must connect the CJS to the 1756-IT6I module at terminals 10 and 14. To
ease installation, wire terminal #12 (RTN-3) before connecting the cold
junction sensor.
Contact your local distributor or Rockwell Automation sales representative to
order additional sensors.
Connecting a Cold Junction Sensor to the 1756-IT6I2 Module
You must connect two CJSs to the 1756-IT6I2 when using an RTB. The
additional CJS offers greater accuracy when measuring temperature on the
module. Connect the cold junction sensors to terminals 3, 4, 17, 18 as shown
in the illustrations.
Contact your local distributor or Rockwell Automation sales representative to
order additional sensors.
