The VT3002-2X/48F is a card holder, not a valve amplifier itself. Bosch Rexroth documentation identifies the VT3002 family as card holders for Eurocard-format electronics, with the 48F variant using a 48-pin Form F connection.
Product Introduction
The Bosch Rexroth VT3002-2X/48F is an open card holder designed to install and wire compatible Eurocard-format electronic control cards in industrial control cabinets. The 2X series covers component series 20 through 29, while the 48F designation identifies the 48-pin Form F connector arrangement.
Its value is mechanical and electrical integration rather than control processing. It provides the physical card support, field wiring interface, and locking arrangement needed by compatible Rexroth electronic cards. That distinction matters when sourcing a replacement: buying an amplifier card when the failed item is actually the holder solves the wrong problem.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A damaged card holder can look like a failed electronics module. Loose terminals, damaged connector contacts, cracked mounting points, or poor card retention can create intermittent faults that are difficult to reproduce. In a hydraulic control cabinet, replacing the electronic card without checking the VT3002-2X/48F holder and its wiring can leave the original fault untouched.
Typical Applications
- Industrial Hydraulics — Mounting Rexroth electronic amplifier and controller cards used for hydraulic valve control.
- Machine Tools — Cabinet installation of Eurocard-format Rexroth control electronics.
- Metal Processing Equipment — Replacement of aging card-holder assemblies in legacy hydraulic control cabinets.
- Factory Automation — DIN-rail or screw-mounted installation of compatible Rexroth electronic cards.
Bosch Rexroth documentation specifically lists the VT3002-2X/48F as an open card holder for compatible controller cards, including use with VT-VSPA2 amplifier-card equipment.
Technical Pitfalls to Avoid
- Do not confuse the holder with the amplifier card.
The VT3002-2X/48F provides the card mounting and connection interface. The actual control electronics are installed in the holder. Bosch Rexroth documentation separately identifies amplifier cards such as the VT-VSPA2 series. - Check the connector code carefully.
The 48F suffix is significant. Rexroth’s family also includes 15H, 32D, 32F, and 64G connection variants. These are not interchangeable simply because they share the base designation. - Respect the terminal-voltage rating.
The documented maximum terminal voltage for the 48F holder is 48 VAC/DC. Do not interpret this as the operating supply voltage of the electronic card installed in it. The card’s own electrical requirements must be checked separately. - Inspect the mating card and connector together.
If the original fault involved intermittent operation, inspect the DIN 41612 contacts, screw terminals, wiring, card guides, locking mechanism, and PCB edge connection before installing the replacement.
Related Products
- Boschth /32D — Another card-holder variant using a 32-pin Form D connector. It belongs to the same 2X holder family but has a different electrical interface, so it is not a direct substitute for the 48F version.
- Boschth /32F — Uses a 32-pin Form F connector. It shares the same general card-holder concept but diffom /48F in connector configuration.
- Boschth /64G — 64-pin Form G version of the holder. Useful when the installed electronic card requires the 64G interface; not a drop-in alternative for a 48F connection.
- Boschth /15H — 15-pin Form H configuration. It belongs to the same card-holder family but uses a different connection arrangement and therefore requires matching hardware.
- Bosch Rexroth VT-VSPA2-1-2X/V0/T1 — Analog amplifier card designed for proportional hydraulic valves. It can be installed uhe /48F holder specified by Rexroth documentation.
- Bosch Rexroth VT-VSPA2-1-2X/V0/T5 — Related analog amplifier-card variant with additional command/ramp functions. It uses the same general card-holder architecture, but its control functions differ from the T1 version.
- Bosch Rexroth VT12302 — Closed card-holder option referenced by Rexroth documentation for applications where an enclosed card-holder arrangement is required. It serves a different mechanical purpose from en /48F.
- Bosch Rexroth VT-NE30-1X — Compact power supply associated with the VT3000 card-holder environment. It is complementary cabinet hardware rather than a replacement for the holder.
Procurement takeaway: /48F is the card-holder assembly, not the control/amplifier PCB. The critical identifiers are , 2X component series, and 48F / 48-pin Form F interface. Bosch Rexroth documentation specifies a maximum terminal voltage of 48 VAC/DC and an ambient range of -20°C to +70°C for the holder.
When replacing one in an operating cabinet, match the connector variant and installed electronic card first. Do not substitute another variant solely because the mechanical housing looks similar.
