Bosch Rexroth VT-VPCD-1-1X/V0/1-0-1 – Digital Pump Controller Amplifier Card
Bosch Rexroth VT-VPCD-1-1X/V0/1-0-1 is a digital closed-loop control amplifier designed for A4VS axial piston pumps with HS4 control and A2V pumps with EO4 control. It delivers electrohydraulic pressure and swivel angle control, plus power limitation for variable displacement pumps in industrial hydraulic systems.
Key Features
- Dual Control Loops: Closed-loop control for pressure and swivel angle (HS4/EO4 pumps).
- Digital Precision: 2 ms scan rate, PWM current-regulated output stage for proportional valves.
- Integrated Diagnostics: Status LEDs, collective fault output, and RS232 (DB9) for BODAC configuration.
- Flexible Setup: Digital inputs for preset parameters; ramp time adjustment for pressure/angle signals.
- Industrial Durability: Euro-card format (100×160 mm), 24 VDC supply, and -10%/+40% voltage tolerance.
