Maximum possible power consumption.
Maximum input values.
Maximum output values. The following figures show how the outputs are used.
Supported relay modes: "Normally Energized" (default), "Normally De-Energized". For

We recommend not to connect the connection cable directly to Ethernet connectors.
Instead the sensor connection cable kit should be used for this purpose.
