The Burkert flow controller module has a PWM control output and cable plug type electrical connection. It operates solenoid valves in the power range from 40mA to 2000mA. It has input signal options of 0-20 mA, 4-20mA or 0-5V, 0-10 V (configurable). The electronics converts an external standard signal into a pulse-width modulated (PWM) signal with which the opening of the valve and hence a fluidic output parameter (e. G. flow rate) can be infinitely varied. Its operating voltage ranges between 12VDC and 24VDC. 2-way valves and control modules: Valves and control modules designed specifically to operate together, provide a valve opening which is proportional to the input signal and allows this to be correlated to the respective operating conditions.
