Product Description:

The VT 3002-2X-48 is an analog amplifier card manufactured by Bosch Rexroth Indramat within the VT 3000 Analog Amplifiers series. Designed for mounting in control cabinets, the unit converts low-level command signals into the controlled current required by proportional hydraulic valves and other electromechanical actuators used in automated machinery. The card plugs into a standardized backplane socket, so individual channels can be integrated through the cabinet backplane without separate point-to-point rewiring. This makes the module a practical interface between higher-level controllers and field devices in hydraulic control systems.

The amplifier channel is rated for continuous loads up to 4 A, so the downstream valve coil can receive stable magnetizing current without external boosters. Terminals and printed traces are insulated for working potentials no higher than 48 VAC/DC, which matches low-voltage control cabinets. Plug-in screw terminals accept conductors up to 4 mm², allowing direct connection of heavier field cables while still permitting easy removal of the card. Internally, the contacts use an even-numbered arrangement that aligns with the VT backplane and keeps the connection pattern consistent. The board mates with a DIN 41612 backplane through a 48-pin connector, and the enclosure clips onto a hat rail for vertical mounting only so convection airflow can pass across the heat-dissipating surface.

Environmental limits range from -20 °C to 70 °C, allowing the amplifier to handle cold starts and elevated cabinet temperatures common in industrial equipment. At only 0.5 kg, the card adds little weight to the rail, which helps when several modules are installed in the same enclosure. The low mass also reduces mechanical loading on the enclosure hardware, while the operating temperature range supports use in compact panels where heat buildup can occur during continuous duty.
