Product Description:

The VT-VRPA2-2-1X/V0/T5 is an electric amplifier card produced by Bosch Rexroth Indramat for the VT-VRPA Electric Amplifiers series. Installed in hydraulic motion systems, the card converts low-level reference signals into regulated current for proportional valve solenoids. That control allows flow or pressure to be adjusted with repeatable accuracy during automated machine cycles.

This amplifier accepts a command value of ±10 V, and the bipolar range lets the controller move valve spools in both directions without added offset circuitry. Four selectable command value call-ups, represented by 4, let a PLC switch among preset operating points during different machine states. All signal paths use analog connectivity, which reduces conversion delay inside closed-loop hydraulic axes.

A dedicated output stage powers up to 2 proportional solenoids at the same time, while a stabilized logic rail from a 24 VDC supply keeps the onboard electronics within tolerance during voltage dips. Device construction uses a printed circuit board format and a 48-pin connector plug, which routes power, feedback, and reference lines through the cabinet interface. Five independent up- and down-ramp generators, shown by 5, shape command edges, and integrated position feedback from external transducers helps linearize valve behavior.
