Buschjost Valves and systems for cleaning dust collectors Norgren Microcontroller-operated valve controller Series 8349120
Valve controller for industrial filters
Description (standard valve)
The solenoid valve controller is used for the time- or differential pressure-dependent control of
solenoid valves in industrial dust extraction technology. Up to 64 valves are controlled with the base
unit and three expansion units. The base unit communicates with the expansions over a RS-485
connection. The valves are activated sequentially and are not chamber-oriented. They are monitored
for excess current and interruption. Errors are displayed on the base unit. The controller is simple
to operate through symbol labelling and LEDs for status and differential pressure indications. The
differential pressure signal is supplied as 4...20 mA value. The controller is available purely as time
controller in a version without differential pressure display. Accessories, such as the differential
pressure sensor, the dp-connection set and the valve connector with various line lengths comple-
ment the controller.
