PWM control Electronics for electromagnetic proportional valves (316522)

Digital control electronics of type 8605 are used to control magnetic proportional control valves in the current range of 40-2000 mA. The electronic device converts an external standard signal into a pulse width modulation (PWM) signal, which allows you to smoothly adjust the opening of the proportional valve and, thereby, the output parameters of the medium flow (for example, flow rate). Due to the internal control of the current through the PWM signal well, a certain value of the effective coil current is compared to each value of the input signal, regardless of the thermal state of the coil. Using the display and control buttons, the electronic device can be easily adjusted to a specific proportional valve and specific application conditions. To integrate the activation device and thus the proportional valve into a higher-level control system, use the CAN-based activation device (buS) option. Setting the parameters and configuration of the proportional valve is quick and easy using the Burkert Communicator software. In addition, the buS control electronics allow the integration of open/close valves. to buS/CAN systems. Thanks to the built-in time relay function, the valve is open/closed. it can be opened or closed for a certain time. This can be used, for example, to regulate volumes in filling processes. As an option, the valve, type 8605, can be equipped with an additional I/O board. It allows you to connect external sensors or switches. The valve response to these inputs can be configured (example: two-position control).
