A convenient, plug-mounted control amplifier for controlling HydraForce proportional valves that have solenoids with DIN 43650A/ISO 4400 electrical connectors.
This control module supplies a proportional valve solenoid with a proportional control signal. The input signal to this controller can be from a 10K potentiometer or a 0–5 VDC source. This economy version has no ramp adjustments. Dither frequency and
amplitude are factory pre-set.
• Mounts directly to solenoid coils with DIN 43650A connectors.
• IP65 weather resistant when used with base gasket (supplied).
• Adjustments accessible with a removable cover.
• One unit covers supply voltages from 9 to 32 VDC.
• No internal fuses; circuit limits current electronically.
• Short circuit proof and reverse polarity protected.
• Connector can be disconnected from coil when powered.
• Maximum current adjustment does not affect minimum current setting.
• Internal supply for potentiometer.
Supply Voltage: 9–32 VDC Coil rating must be matched with supply voltage: RCOIL ≤ (VSUPPLY – 1.5 V) / I-Max.
