5.1 general description
The Digital Control Electronics for proportional valves, Type 8605, (hereinaf-
ter referred to as
Control Electronics, Type 8605 ) is suitable for the control
of all Bürkert proportional valves with a max. current in the range from 40 to
2000 mA.
It transforms an external standard signal into a pulse-width modulated volt-
age signal (PWM) that is supplied to the solenoid coil of the proportional
valve. A given value of the average coil current is thereby assigned to each
value of the input signal. The proportional opening of the valve can be set via
the coil current.
Field of application
The Control Electronics, Type 8605, is designed for continuous operation in
industrial environments, in particular in the fields of open-loop and closed-
loop control engineering.
