6. PRODUCT DESCRIPTION
6.1. Field of Application
The Control Electronics, Type 8605, is designed for con�
tinuous operation in industrial environments, in particular in
the fields of open�loop and closed�loop control engineering.
6.2. General Description
The Digital Control Electronics for Proportional Valves, Type
8605 (hereinafter referred to as Control Electronics, Type
8605) Controls 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 voltage 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.
