Product Description:

The VT 3002-20-48F is an analog amplifier card produced by Bosch Rexroth Indramat in the VT 3000 Analog Amplifiers series. Designed for control cabinets, the module converts low-level command signals into proportional spool currents for hydraulic valves, enabling precise flow and pressure regulation in automated machinery. By fitting into standardized Euro card racks, it supports consistent signal processing across distributed motion or process stations. The card is intended for applications where stable analog control of valve current is needed for repeatable hydraulic response.

Electrical interfacing is governed by the DIN 41612 connector pattern, so the card mates directly with backplanes common in industrial Euro cabinets. The power path supports up to 4 A, which is the maximum continuous coil current the onboard output stage can deliver. Its board outline follows a single Euro format, limiting width and easing card-to-card spacing. Field wiring is accepted through plug-in screw terminals that accommodate conductors up to 4 mm², which suits short low-resistance runs to valve coils. During installation, the board is used in a vertical orientation to preserve convection cooling and keep component labeling readable.

For panel integration, the module supports hat rail or screw mounting, giving a choice between DIN rail clipping and direct chassis fastening. Signal identification on the rear backplane is simplified by an even-numbered pin sequence across the three rows marked d/b/z, which helps keep terminal assignment clear when several cards are placed in the same rack. The front edge carries a 48-pin Form F socket that matches the rack header and maintains an orderly front connection layout. All control circuits are limited to 48 VAC/DC maximum, so cabinet protection can follow a single control-voltage ceiling, and the board’s low mass reduces loading on the card guides during operation.
