EDC-102/10E2 Duplomatic plug-in proportional valve amplifier
EDC-102/10E2 is a digital current amplifier for open-loop control of one proportional hydraulic valve solenoid. This series 10 execution has a 0–5 V command input, a factory maximum current of 780 mA and a factory PWM setting of 200 Hz. It mounts directly on the valve coil connection to EN 175301-803 (DIN 43650), with the standard DIN connector on the PLC side.
Control and adjustment
The amplifier regulates solenoid current in proportion to the reference signal and compensates for changes in temperature and load impedance. PWM control reduces valve hysteresis. Adjust maximum current, offset, PWM frequency and independent acceleration and deceleration ramps using the on-board buttons and display. The optional EDCPC/10 configuration kit, code 3898301001, is ordered separately.
Valve selection and installation
Select the amplifier maximum current and PWM frequency against the exact valve coil specification. One EDC-1 controls one solenoid; a two-solenoid valve requires two amplifiers and suitable command logic. Valves with integrated electronics use their own electronic driver. The regulated and filtered supply must remain within 10–30 V DC, including ripple, and must be higher than the connected solenoid's rated working voltage, as specified in the manufacturer catalogue. Required power depends on supply voltage and output current.
This ordering code uses the standard DIN connection on the PLC side. The voltage input is 0–5 V; use a matching controller output.
