The Valve Drive Actuators VAA/S are
modular installation devices in Pro M
Design for installation in the distribution
board on 35 mm mounting rails. The
devices feature six or twelve
semiconductor outputs for control of
Thermoelectric Valve Drives in heating
and cooling systems. The outputs can be
operated at 24...230 V AC.
The outputs are short-circuit and overload
protected.

Caution:
When valve drives (e.g. TSA/K) are connected in
parallel, the technical data of the respective
valve drive must be observed! The inrush current
(750 mA) or rated current (160 mA) of the output
may not be exceeded.

The outputs can be directly controlled
using the manual buttons. The LEDs on
the front of the device signal the status
of the outputs.
The connection to the ABB i-bus
is implemented via a bus connection
terminal.
The devices do not require an additional
auxiliary power supply.
