Note
Industrial Ethernet OSM TP62 is available in two versions:
• OSM TP62 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 8 device
LEDs, there is an additional display mode known as the "Input Status" that is
selected using a third mode LED.
• OSM TP62 without digital inputs:
There are no digital inputs and the "Input Status" display mode is not available.
The operating states are displayed by 2 mode LEDs.
