The digital inputs have free of potential contacts (opto-isolated).
By default, the digital inputs are disabled.
In a master-master filter arrangement, only the master that has the control over the complete system will monitor its
digital outputs. For full redundant functionality, it is recommended to cable the digital inputs of all the units in the filter
system.

The digital outputs contacts have a common point and are of the NO-type (normal open). The contact ratings are:
Maximum continuous ac rating: 440 Vac/1.5 A;
Maximum continuous dc rating: 110 Vdc/0.3 A;
The common is rated at 9A/terminal, giving a total of 18 A.
Information on cabling the digital output contacts and on setting up the digital outputs with the PQF-Manager is given
in the detailed manuals.
