Connector Pin
Arrangement
The arrangement of the connectors is shown in the following diagram.
Wiring Attach MOLEX connectors to the Transistor Input Unit and connect them to
external devices.
Applicable Connectors
Wiring Example
Note V terminals and V connector pins, as well as G terminals and G connector
pins, are internally connected. When the I/O power is being supplied from a
terminal block, the power can be supplied to the input devices from the V and
G connectors. Current supplied in this way, however, must be less than 1 A.
