Industrial 71530233B PB-X-J-A-14 Amplifier Module

The Tokimec 71530233B PB-X-J-A-14 Amplifier Module is a PCB-based proportional valve amplifier in the PB-X Series designed for open-loop control of hydraulic proportional valves. It is used in hydraulic power units and automation equipment such as injection molding machines, CNC machine tools, industrial presses, and factory automation systems to regulate current to proportional solenoids for precise hydraulic motion. Key specifications include 24 V DC ±5% supply, input 0–10 V DC with 24 kΩ input impedance, output current 0–1 A, and load resistance 14–19 Ω, with a 0–400 mA peak-to-peak dither at 100–120 Hz, and mounting as a PCB module. Common replacements for compatibility include Tokyo Keiki PB-X-A-20, PB-Z-A-14, and Eaton Vickers KDG4V proportional valve amplifier modules.
