3.1.9 Analog I/O option MCB 109
The Analog I/O card is to be used in e.g. the following
cases:
•
Providing battery back-up of clock function on
control card
•
As general extension of analog I/O selection
available on control card, e.g. for multi-zone
control with 3 pressure transmitters
•
Turning frequency converter into de-central I/O
block supporting Building Management System
with inputs for sensors and outputs for operating
dampers and valve actuators
•
Support Extended PID controllers with I/Os for set
point inputs, transmitter/sensor inputs and
outputs for actuators.
