Proportional valve module 750-632 simplifies connection of hydraulic or pneumatic valves with flexible valve-control operation modes. Two single-coil valves or one dual-coil valve can be controlled uni- or bidirectionally. For each channel or coil, the output current is 2 A in one-channel operation and 1.6 A in two-channel operation. It has two current-controlled pulse-width modulation outputs (24 V) with adjustable dither. Discrete dither frequency setting minimizes the motion, which is adjusted to the valve around the rest position, allowing the setpoint to be defined without considering static friction.
