5- pole connector strip
Via the connector strip with the terminal numbers 1 to 5 the signal input for the standard
signals and the sensor supply are connected.
4.3.1.
Input for standard signals
The input signal is connected to terminals 3 to 5. The
AK-M2-VVR4C
has a voltage input
and a current input to which most conventional sensors with a standard signal output can
be connected. The input is galvanic isolated from the power supply (auxiliary voltage) and
the sensor supply.

Sensor supply
The 24 VDC sensor supply is available at terminals 1 and 2. The sensor supply is galvanic
insulated from the measuring input. Current loop sensors (2-wire) and 3-wire and 4-wire
sensors can be operated via the sensor supply as long as their current consumption is not
higher than 50 mA (Power consumption < 1.2 VA).
