Product Description:
The VT 3000 S 35 is an analog amplifier card manufactured by Bosch Rexroth Indramat as part of the VT 3000 Analog Amplifiers series. Installed in a modular rack, the card interfaces between a machine controller and proportional solenoid valves. It converts reference commands into a regulated current that positions or meters hydraulic actuators, enabling closed-loop speed, force, or pressure control in industrial automation cells such as presses, plastics machines, and conveyor systems while maintaining electrical isolation between the logic level circuitry and the high-power valve coils.
Normal operation is supported by a supply of 24 VDC ±10%; within this envelope the internal circuitry draws up to 30 W to power signal-conditioning stages and output drivers. The driver channel can deliver a peak of 800 mA so that high-response proportional coils achieve full stroke without external boosters. A front-mounted fuse rated at 2.5 A protects the card from sustained overloads or wiring faults and can be replaced without withdrawing the board. Command information is received as a differential reference of 10 V, allowing noise-immune transmission over shielded pairs in electrically noisy plant environments.
Fine adjustment is handled through four onboard potentiometers that scale the incoming control span of ±9 V to match individual valve characteristics while honoring a maximum coil resistance of 19.5 Ω; staying below this limit ensures the amplifier can deliver programmed current without saturating. Thermal stability is aided by a temperature drift figure of 0.5 ‰/K, so output does not deviate appreciably as ambient conditions vary. All electrical connections are routed through a back-plane compatible 32-pin Eurocard connector, and the 0.15 kg module occupies seven 5.08 mm divisions on the component side and one division on the conductor side of the rack.
