Connecting a CJC via a Removable Terminal Block
When using an RTB, if you choose to connect CJC sensors to your module, you
must connect a CJC sensor at the top of the RTB and one at the bottom of
the RTB.
IMPORTANT
Remember the following:
• Connect the white end of the CJC sensor to the even-numbered terminals.
For CJ 0, connect the white end to terminal 2. For CJ 1, connect the white
end to terminal 36.
• Connect the orange end of the CJC sensor to the odd-numbered terminals.
For CJ 0, connect the orange end to terminal 1. For CJ 1, connect the orange
end to terminal 35.
• Two CJC values indicate the temperature of the top and bottom CJC sensor
• CJC sensor temperatures are indicated in degrees Celsius.
