EMERSON – ASCO Solenoid Controller for Process Valve for use with Proportional solenoid valve

ISO 4400 / EN 175301-803, form A / IEC 335. Control unit for POSIFLOW solenoid valve. Proportional electronic control unit for POSIFLOW solenoid valve. Converts analogue input control signals of a solenoid by means of pulse width modulation. Valve closure function at less than 2% of the maximum control signal. Adjustable ramp control. Coil supply current is independent of coil resistance (temperature) and supply voltage variations. Coil supply current can be adjusted based on control signals. Electronic circuit is integrated in a unit that can be connected to a 3-terminal coil.
