Device technology
The Electronic Switch Actuator ES/S 4.1.2.1 is a modular installation device
in Pro M design. The device features four semiconductor outputs for control
of thermoelectric valve drives in heating and cooling systems. The outputs
can be operated with either DC or AC voltage (24...230 V AC/DC).
Each output is short-circuit and overload protected. The outputs can be
directly controlled using the manual pushbuttons. The LEDs on the front
of the device signal the status of the outputs.

The number of connectible valve drives per
output is dependent on the maximum inrush
current (8 A) or continuous current (1 A) of
the output. They may not be exceeded when
several valve drives are connected in parallel.
Observe the technical data for the valve drive.
