Output to PLC - Current Sourcing
To configure the output as a sourcing output, connect OUTPUT COMMON (for example, OUTPUT COMMON 2) to the
high voltage reference (+24VDC) and connect one of the OUTPUTS (for example, OUTPUT 4) to the INPUT of the
photoelectric sensor or PLC. When the output turns ON, the PLCinput is pulled up to a high voltage level.
Note:
l OUTPUTS 0 - 7 provide up to 50mA current (maximum). These outputs are typically connected (directly or
indirectly) to an input, such as a trigger input or PLC input.
l There are four sets of outputs: OUTPUTS 0 - 3 share the OUTPUT COMMON 1 connection; OUTPUTS4 - 7
share the OUTPUT COMMON 2 connection; OUTPUTS 8-11 share the OUTPUT COMMON 3 connection;
and OUTPUTS 12 - 15 share the OUTPUT COMMON4 connection. Therefore the output devices for each
set of outputs must be the same; either current sinking or current sourcing.
l 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 PC. 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.
