The DV2 module features 16 binary inputs connected to ground and 6 relay outputs. When a binary input is activated, or when a relay contact is closed, the corresponding LED lights up.
The parameters of the outputs and binary inputs are configured in the connected H3 unit. One of the H3 unit’s preset functions is direct support for pump failover in the event of a failure in one of the pumps and for their regular rotation.
Unlike the binary inputs on the H3 unit’s connection board, the DV2 inputs are not combined pulse-binary inputs; therefore, an output from, for example, a pulse water meter cannot be connected to them.
