3.23 Parameters 26-** Analog I/O Option
MCB 109
The VLT
®
Analog I/O Option MCB 109 extends the
functionality of VLT
®
AQUA Drive FC 202 Series frequency
converters by adding some extra, programmable analog
inputs and outputs. This is useful in control installations
where the frequency converter may be used as decentral
I/O, obviating the need for an outstation and thus reducing
cost. It also provides flexibility in project planning.
NOTICE
The maximum current for the analog outputs 0–10 V is 1
mA.
NOTICE
Where live zero monitoring is used, it is important that
any analog inputs not being used for the frequency
controller, for example being used as part of the building
management system decentral I/O, have their live zero
function disabled.

analog outputs, and control the relays, using communi-
cation via the fieldbus.

On-board real-time clock setting
The VLT
®
Analog I/O Option MCB 109 incorporates a real-
time clock with battery back-up. This option can be used
as back-up of the standard clock function included in the
frequency converter. See
parameter group 0-7* Clock
Settings .
Use the MCB 109 for control of devices such as actuators
or valves, using the extended closed-loop facility, thus
removing control from the existing control system. See
parameter group 21-** Extended Closed Loop . There are 3
independent closed-loop PID controllers.
