Product Description:
The VT 3000-3X-SO43A-1635 is an analog amplifier card manufactured by Bosch Rexroth Indramat for the VT 3000 Analog Amplifiers series. This plug-in unit fits DIN-rail carriers and serves as the interface between a machine controller and a proportional hydraulic valve, converting differential command voltages into controlled solenoid current. Within an automated hydraulic circuit, the card enables stable valve positioning and repeatable pressure regulation while operating from a single 24-volt supply. Its compact board format allows dense packing inside control cabinets used on presses, die-casting machines, and assembly lines.
The control section accepts a differential reference of ±9 V, and the input remains linear because the card expects a minimum load of 500 Ω at the terminals. Internal regulation draws power from a supply of 24 VDC ±10%, and the circuitry limits valve drive to a peak of 800 mA. When matched with a maximum coil resistance of 19.5 Ω, this setting keeps the device within its 30-watt thermal limit. A calibrated test point is provided for current checks, and every 1 mV measured there equals 1 mA delivered to the solenoid, allowing quick adjustment without breaking the circuit.
The output stage is pre-biased at 20 mA so the valve remains centered when no command is present. Protection is supplied by a 2.5 A fuse in a 5 × 20 mm glass cartridge, which isolates the card if the load shorts. The board consumes up to 30 W, and its gain remains stable with a temperature drift of only 0.5‰/K. Physical integration follows DIN 41612 spacing rules: the component side occupies 7 divisions, the conductor side 1 division, and the face plate covers 8 divisions with a 5.08 mm division pitch, allowing adjacent modules to clear cabling. The assembled card weighs 0.15 kg, which minimizes stress on lightweight rail carriers.
