Internal Product Review
The VT 3000 S 34 is a Bosch Rexroth Indramat analog amplifier with a 24 VDC ±10% supply and a modest 30 W power requirement. A 10 V differential input and 800 mA maximum output current support precise, responsive control in hydraulic drive circuits. Low temperature drift of 0.5‰/K makes the unit a strong choice for stable analog performance.

Product Description:
The VT 3000 S 34 analog amplifier fits a 32-pin Eurocard rack and belongs to the VT 3000 Analog Amplifiers series manufactured by Bosch Rexroth Indramat. It serves as an interface between a motion controller and a proportional hydraulic valve. The unit boosts small reference voltages into controlled coil current so that the valve spool follows the commanded position in real time during hydraulic automation loops.
The card draws its logic and power-stage energy from a supply of 24 VDC ±10%, which allows ordinary 24 V utility buses to tolerate voltage sag or rise without affecting output accuracy. A board-mounted fuse rated at 2.5 A protects the conductors against short circuits that could otherwise damage the driver stage. During operation, the amplifier can deliver up to 800 mA of load current, enough to actuate proportional solenoids whose coil resistance does not exceed 19.5 Ω. Overall consumption tops out at 30 W, so power supplies and cabinet heat dissipation can be sized with predictable margins. The card accepts an input control span of ±9 V and maintains a minimum bias current of 20 mA to keep the valve in its linear region when no command signal is present.
A differential command input of 10 V is processed through internal feedback, and the amplifier presents a minimum input load of 500 Ω minimum to prevent undue strain on upstream PLC outputs. Temperature drift is limited to 0.5‰/K of fmax, which helps maintain repeatable flow control as the machine warms up during operation. The board weighs only 0.15 kg, allowing dense stacking without overloading card guides. Mechanical layout rules still require 7 divisions of component clearance, 1 division between conductors, and an 8-division face plate to maintain safe isolation and provide convenient front-panel access to the 32 connector pins.
