Product Description:
The VT 3000 36A is an analog amplifier card manufactured by Bosch Rexroth Indramat for the VT 3000 Analog Amplifiers series. VT 3000 36A serves as a signal-conditioning stage that turns voltage references from a machine controller into proportional current for hydraulic valve coils in industrial automation. Mounted on a 32-pin Eurocard, the board installs beside other control electronics so that the valve loop can be tuned with on-board potentiometers instead of external power packs. The module's closed-loop circuitry helps maintain stable spool positioning during pressure fluctuations.
The power stage receives a single 24 VDC supply that feeds the output transistors and signal conditioning circuits. The command channel accepts a symmetrical ±9 V reference relative to the board's zero rail, while a built-in differential input range of 10 V allows noise-immune operation in long cable runs. The signal conditioner presents at least 500 Ω of input impedance to avoid loading upstream electronics. Inside the current loop, a bias circuit guarantees a minimum output of 20 mA, giving an initial pilot flow even at zero command. Under full demand, the amplifier can source up to 800 mA to a load coil whose resistance must not fall below 19.5 Ω, preventing excessive dissipation in the output transistor.
For panel integration, the card occupies an eight-division slot on a DIN front plate, with each division measuring 5.08 mm, so the rack must provide 40.64 mm of width. A replaceable 2.5 A fuse on the board safeguards the incoming supply rail against downstream faults, while the total heat generated remains within 30 W during continuous operation. Thermal stability is aided by a drift coefficient of 0.5 ‰/K, maintaining consistent output despite ambient changes. The assembly weighs just 0.15 kg, which keeps handling simple during installation and service.
