1. When using the 1794-TBN and -TBNK, an auxiliary terminal block must be used to provide connection points for each channel's second sensor wire,
120V ac common. Use B-33 and C-51 for daisy chaining to the next terminal base unit.
For TB2, -TB3, -TB3K and -TB3S:
A = Output terminals.
B = B-17 through B-32 are connected internally to 120V ac common L2. Connect 120V ac common L2 to B-16.
C = Power terminals (C-34 and C-51 for TB2; C-34 through C-51 for TB3 and TB3S) are connected internally. Connect 120V ac L1 to terminal C-34.
For -TBN and -TBNK: Connect 120V ac common L2 to B-16. Connect 120V ac L1 to C-34.
B = Even numbered output terminals 0 through 14; B-16 and B-33 are connected internally.
C = Odd numbered output terminals 1 through 15; C-34 and C-51 are connected internally.
