PARKER PCD00A-400-22 Digital Proportional Valve Amplifier

Overview

PARKER PCD00A-400-22 is a dual-channel digital amplifier module for Parker proportional pressure and throttle valves without position feedback. PARKER PCD00A-400-22 receives analog command signal from PLC or HMI, generates regulated drive current for two proportional solenoids, and supports ramp control, dither adjustment and internal preset command selection. This PARKER PCD00A-400-22 is widely stocked as spare hydraulic proportional drive amplifier for industrial hydraulic automation assemblies.

Features

PARKER PCD00A-400-22 Amplifier Module provides two independent output channels, each channel configurable separately for pressure or flow control. It accepts 0–10VDC analog command input and four digital switch inputs for selecting stored internal setpoints. PCD00A-400-22 supports adjustable acceleration ramp, deceleration ramp, minimum current limit, maximum current limit and dither amplitude and frequency setting to reduce valve hysteresis and improve response linearity. It has one collective status output for fault and enable feedback to the host control system. Parameter configuration is completed via RS232 serial port and dedicated Parker software. It adopts snap-on DIN rail mounting with detachable screw terminal blocks for convenient wiring and replacement. It is EMC compliant, CE certified, designed for 24/7 continuous operation in injection molding machines, die-casting machines, presses and test bench hydraulic cabinets.

Principle

PARKER PCD00A-400-22 receives analog reference signal or digital preset selection signal. This Digital Proportional Valve Amplifier calculates the target solenoid current according to configured parameters and ramp curve, outputs stable regulated current to the proportional valve solenoid. The dither signal superimposed on the drive current reduces spool friction. The module monitors enable condition and internal fault, and changes the status output state when abnormal condition occurs.

Applications

PARKER PCD00A-400-22 is deployed in hydraulic press, injection molding machine, metal forming equipment, hydraulic test bench and material handling hydraulic systems. It drives Parker proportional pressure valves and proportional throttle valves. PARKER PCD00A-400-22 is stocked as spare proportional amplifier for hydraulic control assemblies.
