Product Description:
The VT-VRPA2-1-12/V0/T1 is a plug-in electric amplifier card from Bosch Rexroth Indramat and belongs to the VT-VRPA Electric Amplifiers series. Installed in a 19-inch rack, it interfaces between a motion controller and a proportional directional valve, specifically the 4WRE 6...-2X family, to generate precise spool-positioning currents. By converting low-level command voltages into controlled coil drive, the card regulates hydraulic flow and pressure in industrial automation loops that require repeatable response and compact electronic integration.
The card operates from a nominal supply of 24 VDC (+40%/-20%); internal regulators maintain operation from the lower limit of 18 V to the upper limit of 35 V. Input protection is provided by a 2 A medium-time-lag fuse, and overall current draw remains below 2 A, keeping cabinet power requirements predictable. Signal interfacing is provided through a 48-pin DIN 41612 design F header, and the board dimensions of 100 × 160 mm match Eurocard subracks. An internal oscillator operating at 5.6 kHz ±10% drives the pulse-width modulation stage that energizes the valve coils. The command channel presents a 100 Ω current input load, while the differential voltage input exceeds 50 kΩ to minimize source loading. A 10 kΩ ramp input allows external slew-rate shaping during acceleration and deceleration phases.
For closed-loop control, the amplifier supplies a ±10 V ±2% command signal to the valve electronics and monitors feedback through an ±2.5 V ±2% actual-value output, enabling accurate comparison within the drive controller. Total power demand is limited to <24 VA, so thermal loading in densely populated racks remains modest. The assembly weighs only 0.17 kg, making the card easy to handle during rack service. Compatibility with the designated hydraulic valve supports repeatable metering characteristics without additional calibration stages. The high input impedances preserve the fidelity of external setpoint generators and reduce unwanted loading on connected control circuits.
