Product Description:

The VT 1610-3X/E1/4WRD10-3X is a plug-in servo amplifier card produced by Bosch Rexroth Indramat within the VT 1600 Servo Amplifiers series. The card is intended for installation in standardized Eurocard racks, where it conditions command signals and supplies controlled current to attached electromechanical or hydraulic actuators used in industrial automation. Its modular format allows front access in the control cabinet without rewiring the backplane. This arrangement lets the amplifier remain part of a centralized control system while the connected actuator responds to low-level command changes from the host controller.

It interfaces to the system bus through a DIN 41612 Form D, 32-pole connector, providing a secure electrical connection while maintaining signal integrity. The board’s supply demand is limited to <200 mA, which eases loading on low-power control supplies. An integrated oscillator operates at 5 kHz; this frequency sets the pulse modulation used for current regulation. Stable signal conditioning helps the amplifier maintain predictable response when it is used with proportional valves or similar control elements. The front panel includes an analog ammeter scaled to ±30 divisions, providing a direct visual indication of output current. Under closed-loop conditions, the card can deliver up to ±60 mA of valve or coil current, and this range is matched to proportional devices that need symmetrical drive signals. That output behavior is suitable for applications that depend on balanced bidirectional actuation rather than simple on-off switching.

Dynamic behavior is further refined by a 340 Hz / 3 mAss dither signal that reduces static friction in proportional valves. Voltage reference rails are stabilized by a ±15 V regulator, so temperature-related supply drift does not disturb the setpoints. The regulated internal rails also help preserve repeatable command processing as ambient conditions change during operation. The relay stage inside the card uses a coil with 2000 Ω resistance, and its switching sequence completes within a 1 ms duty cycle for prompt enable or shutdown commands. English legends are printed on the front plate for straightforward setup, and the Eurocard rack and card holder format supports guided insertion to protect the edge contacts.
