The digital control electronics, Type 8605, serves to operate proportional solenoid control valves in the power range from 40 - 2000 mA. The electronics converts an external standard signal into a pulse-width modulated (PWM) signal with which the opening of the proportional valve and hence a fluidic output parameter (e.g. flow rate) can be infinitely varied. An internal current control with the duty factor of the PWM signal as manipulated variable ensures that every value of the input signal, irrespective of the thermal condition of the coil, is unambiguously assigned a given value of the effective coil current. A display and operating keys allow the electronics to be easily adapted to a particular proportional valve and to the concrete conditions of an application.
