TC-602/702/604/704 (60 Channel Input)
These cables are idented CH0 to CH61 with six (interconnected) 0V wires. Channels 41 to 60 are
connected to two separate pins on the module socket as listed in the table above. This is because the
60 channel modules use a similar field PCB to the 40 channel modules but distribute two circuits to
each channel instead of three. Channels 0 and 61 are internal reference channels and should not be
connected.
