128 input/ output signal pins.
P-0/1 - P-E/F Connect the positive side of the external power supply.
These pins are common to 16 input/ output signal pins.
N-0/1 - N-E/F Connect the negative side of the external power supply.
These pins are common to 16 input/ output signal pins. One pin permissible current of the connector is 0.3A. Please connect necessary number of pins for the corresponding total current of the input/
output 16 channels. When 16 channels are used by the output full ratings (100mA per 1 channel), it is necessary to connect six all.
N.C. This pin is left unconnected.
