MAC-LINK input-output card
The MAC-LINK Input/Output Card family is designed to extend the basic functionality of
building pressure differential systems. MAC-LINK cards use the existing communication
infrastructure of the fireBUS® pressure differential system on site. The u
se of cards in a separate
housing provides flexibility in the choice of place of installation and significantly reduces the
number and length of connection cables. The differential pressure system ensures continuous
monitoring of the cards' status and signals of their failure. Depending on the needs, the cards can
be equipped with a different number of inputs and/or outputs. MAC-LINK cards also allow you to
increase the number of analog inputs or outputs, for example for MAC-FC or MAC-D-MIN
controllers.
MAC-LINK family cards can have the following inputs/outputs:
•
I - digital inputs, with optional line fault monitoring;
•
IA - analog inputs;
•
O
–
digital outputs;
•
OA
–
analog outputs.

MAC-LINK cards can be found in the following subtypes, depending on demand:
•
MAC-LINK I card with inputs only;
•
MAC-LINK O card with outputs only;
•
MAC-LINK I/O card with inputs and outputs.
