Bosch Rexroth VT5011 Proportional Valve Amplifier Card

The Bosch Rexroth VT5011 Proportional Valve Amplifier Card is an analog amplifier module used to drive Rexroth proportional valves as part of the Rexroth VT family of valve amplifiers. Rexroth’s cross‑reference materials show the VT5011 (and VT5012) can be upgraded or substituted by newer amplifier series such as VT‑VRPA1 and VT‑VSPA1 families, depending on valve type and size (for example VT‑VRPA1‑50/51/52‑1X series replacements). A related variant, VT5011S42, is listed by Indramat as a proportional amplifier module within the VT1600 servo amplifier ecosystem and described as a control card for hydraulic motion systems. Retailers also explicitly list VT5011 as a Rexroth valve amplifier card, underscoring its role in legacy proportional valve control configurations. This family‑to‑family mapping reflects Rexroth’s approach of preserving compatibility while migrating to newer amplifier platforms across proportional valves.
