3.20.1 Analog I/O Option MCB 109, 26-**
The Analog I/O Option MCB 109 extends the functionality
of
VLT Refrigeration Drive FC 103 Series frequency
converters, by adding a number of additional,
programmable analog inputs and outputs. This could be
especially useful in Building Management System instal-
lations where the frequency converter may be used as
decentral I/O, obviating the need for an outstation and
thus reducing cost.
