Note
Industrial Ethernet OSM ITP62-LD is available in two versions:
• OSM ITP62-LD with eight digital inputs:
The eight digital inputs are connected over two plug-in 6-pin terminal blocks on
the top of the device. To display the status of these inputs using the eight
device LEDs, there is an additional display mode known as the "Input Status"
that is selected using a third mode LED.
• OSM ITP62-LD without digital inputs:
There are no digital inputs and the "Input Status" display mode is not available.
The operating states are displayed by two mode LEDs.
