DATA SHEET PWM Control Electronics for Solenoid Control Valves • Programmable digital electronics • Converts an anaog input signal to a PWM output signal • Adjustable PWM frequency • Digital communication possible (büS) • Optional integrated time control and digital/analog input signals Product variants described in the data sheet may differ from the product presentation and description. Type description 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 valve control signal 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 buttons allow the electronics to be easily adjusted to a particular proportional valve and to the concrete conditions of an application. In order to integrate the control electronics - and thus the solenoid control valve - into a higher-level PLC system, a CAN based version (so called büS) is available. The parameterization and configuration of the solenoid control valve can be done quickly and easily by the Bürkert Communicator software. Furthermore, the büS control electronics allows to integrate shut-off valves into büS/CAN systems. By using the integrated time control function, a shutoff valve can be opened or closed for a certain time period. This serves, for example, batch control solutions in filling. As an option, Type 8605 can be equipped with an additional I/O board. This makes the connection of external sensors or switches possible. The behaviour of the valve on these input signals can be configured (e.g. 2-point control). 1000086949 | Standard | EU | en | 202001 | 10 © Christian Bürkert GmbH & Co.
