Product Description:
The VT 2000-48 E2 is a proportional amplifier card manufactured by Bosch Rexroth Indramat and supplied within the VT 2000 Proportional Amplifiers series. Mounted in a standardized plug-in frame, the card interfaces between a low-level control signal and the field solenoid of a hydraulic valve. It converts voltage references into stable coil current so that flow or pressure can be adjusted with repeatable accuracy in automated machinery.
The card normally operates from a nominal 24 VDC source. Built-in tolerances permit continuous operation from the 22 V lower threshold to the 35 V upper threshold, preventing nuisance trips during line dips or surges. A time-delay 2.5 A T fuse on the card edge limits fault energy and protects the board’s low-impedance outputs. The card has Eurocard dimensions of 100 × 160 mm, and all command, feedback, and power leads terminate on a single 32-pin male connector to simplify rack wiring. Despite its drive capability, the amplifier draws less than 1 A and consumes less than 25 VA, so cabinet power demand and heat dissipation remain modest. Separate front-panel trimmers scale the +9 V and +10 V full-scale inputs to match upstream controllers, while an internal regulator stabilizes the ±9 V reference rails for the signal stages.
The output stage supplies up to 800 mA of controlled current to a valve coil with a resistance of 19.5 Ω, supporting linear force generation across the valve stroke. For offset adjustments, a separate bias network can deliver up to 300 mA independently of the command input, allowing the machine to maintain zero flow when required. The high-impedance command port presents 100 kΩ to the upstream controller, reducing the electrical load on sensitive analog sources. The complete assembly has a mass of 0.1 kg, which minimizes stress on the card guides and backplane connectors while keeping the rack assembly lightweight.
