Wire Inputs and Outputs

The following figures show basic wiring for some of the more common I/O configurations.

Input from PLC - Current Sinking

To configure the input as a sinking input, connect INPUT COMMON (for example, C1) to the high voltage reference

(+24VDC) and connect one of the INPUTS on the same terminal row (for example, INPUT 0) to the OUTPUT of the

photoelectric sensor or PLC. When the PLC output turns ON, the INPUT is pulled down to a low voltage level.

Note

There are two input terminal rows. INPUTS 0 - 3 share the COMMON 1 connection and INPUTS 4 - 7 share

the COMMON 2 connection. Therefore the input devices for each terminal row must be the same; either

current sinking or current sourcing.

To maintain optical isolation of the I/O lines, the devices connected to these lines must not be connected to

the same power supply as the vision controller. If they are connected to, or share a ground with, the same

power supply, they may still function but will no longer be optically isolated.
