0-10 VDC Input (0–10 VDC I)

A DIN rail-mount style control amplifier for controlling HydraForce proportional valves. Remote mounting in a protected enclosure is required.

Product Operation

This control module uses closed-loop current control with superimposed dither to supply a proportional valve solenoid with a proportional control signal. The input
signal to this controller can be from a 0–10 VDC source.

Product Features

• Adjustments and connections clearly labeled.• LED indication of output power level, input level and power on/off.
• One unit covers supply voltages from 9 to 32 VDC.
• No internal fuses; circuit limits current electronically.
• Short circuit proof and reverse polarity protected.
• Can be disconnected from coil when powered.
• Maximum current adjustment does not affect minimum current setting.
• Independent ramp adjustments.• Filter eliminates electrical noise.
• Dither frequency and amplitude are adjustable for maximum valve performance.
