Product Description:

The VT3002 analog amplifier card belongs to the VT 3000 Analog Amplifiers series produced by Bosch Rexroth Indramat. Inside electro-hydraulic control cabinets, the module shapes command voltages and supplies proportional current to matched valve coils, serving as the link between a machine's electronic controller and its hydraulic actuators. It occupies a single slot in a DIN backplane and is used to automate pressure, flow, and directional functions for presses, plastics machinery, and assembly systems where closed-loop hydraulic accuracy is required.

For low-power proportional stages, the card delivers up to 3 A of continuous coil current when equipped with form G output components, while heavy-duty form H versions extend that capacity to 15 A. Both variants share a terminal rating of 48 VAC/DC, ensuring the screw terminals never exceed the insulation limit of the board. Field wiring up to 4 mm² can be landed without ferrules, and installation is simplified because the housing can fasten by either screw or snap-on hat-rail mounting without separate brackets. These values match the amplifier to coil resistance, the supply source, and the available panel space in multi-axis hydraulic drives.

Additional operating limits apply to the remaining output forms. Medium-power forms D and F permit a continuous output of 4 A, giving designers a midpoint between the light and heavy versions without changing the board outline. Operation can start at -20 °C for cold-start press lines and may rise to 70 °C before derating becomes necessary, so cabinet ventilation must match this range. Signal and power paths terminate on a backplane connector that follows the DIN 41612 standard, allowing direct mating with standard Rexroth card racks while maintaining even-numbered pin parity for predictable wiring.
