Product Description:
The VT 1610-3X/E1/4WRD16-3X is a servo amplifier card produced by Bosch Rexroth Indramat for electro-hydraulic control loops in the VT 1600 Servo Amplifiers series. The board conditions analog command signals and drives proportional spool valves to support closed-loop position or pressure regulation without separate control electronics. It fits into a standard 19-inch rack alongside other motion-control modules, giving hydraulic presses, extruders, and similar automation systems a compact way to manage valve current control from a centralized cabinet. Because the card works inside a rack-based platform, it can be combined with companion modules for monitoring, control, and signal distribution in larger hydraulic systems.
The amplifier draws a maximum of <200 mA from the rack supply, leaving headroom for additional cards on the same backplane. Inside the circuit, a crystal-controlled oscillator operates at 5 kHz, generating the carrier that the modulator converts into valve drive current. A superimposed dither of 3 mAss at 340 Hz minimizes static friction in the hydraulic spool and improves proportional resolution. This modulation method helps the valve respond smoothly to changing command levels during low-speed or fine-positioning movements. The output stage can source or sink ±60 mA, which is suitable for most size-16 pilot and main valves without external boosters. Installation is straightforward because the board follows the Eurocard format and engages a DIN 41612 Form D connector that handles power, command, and feedback lines. All adjustment legends on the front plate are printed in English, reducing setup errors.
Signal routing through the connector uses 32 dedicated poles that keep analog references separate from power rails to help limit interference. An onboard relay with a coil resistance of 2000 Ω engages the enable path, and its actuation time of 1 ms supports rapid shutdown when the control system detects a fault. The card also integrates a regulated supply of ±15 V that can be shared with external position sensors, which removes the need for a separate field power pack. This arrangement lets the rack provide command handling, valve drive, and sensor support from one control location. Centralizing these functions on the card also helps simplify wiring inside the enclosure.
