Product Description:
The VT-VRPA1-527-20/V0/2/2V is an electric amplifier card manufactured by Bosch Rexroth Indramat for the VT-VRPA Electric Amplifiers series. Installed in a modular rack, it conditions low-level control signals and drives proportional solenoids that regulate hydraulic flow or pressure in automated machinery. By translating bipolar setpoints into regulated coil current, the board enables closed-loop positioning and force control for electrohydraulic actuators used throughout industrial automation. This signal conversion allows a connected controller to command hydraulic motion while the amplifier manages the electrical requirements of the solenoid.
Setpoint and feedback processing centers on a differential input that accepts ±10 V and presents an impedance of 100 kΩ, so upstream PLC analog outputs are not heavily loaded. The amplifier operates from a nominal 24 VDC supply and draws up to 1.5 A. Internal regulation also creates positive and negative 15 V rails for position transducers. A smoothing network built around a 4700 µF capacitor filters the supply bus, and the capacitor is rated for 63 VDC to withstand overvoltage. Current modulation is optimized for hydraulic coils, with a continuous solenoid current of 1.5 A and a peak current of 2.7 A. The associated power channel is rated for 40 VA. The front panel has a width of seven modular spaces, allowing the card to fit standard Eurocard subrack layouts.
The board measures 160 mm in depth and 100 mm in height. It connects to the backplane through a DIN 41612 F32 connector that carries power, command, and feedback lines. Typical power dissipation is 37 W, which must be considered when planning airflow and heat removal within the cabinet. The reference generator provides a bipolar 10 V output at 10 mA for external scaling networks, and a 10 kΩ potentiometer can be connected as the signal source. Pilot feedback enters through an input stage with an impedance of 20 kΩ. The fault-output transistor can switch up to 100 mA to signal coil overcurrent or a loss of position feedback. Actual-value monitoring uses the same voltage range as the command channel, allowing both signals to be compared with compatible measuring equipment.
