It is part of the VT 1600 Servo Amplifiers series and operates with a ±24 V supply voltage and a power supply current of less than 200 mA. The amplifier includes three PID potentiometers and an installed voltage regulator.
Internal Product Review
The VT 1600-3X-E1 is a well-executed servo amplifier featuring a ±24 V supply and an installed voltage regulator. A 340 Hz dither frequency with 3 mAPP amplitude supports smooth valve actuation and consistent control behavior. Low power supply current below 200 mA and a 32-pin connection layout make the amplifier especially appealing for efficient industrial integration.

Product Description:
The VT 1600-3X-E1 servo amplifier is manufactured by Bosch Rexroth Indramat and belongs to the VT 1600 Servo Amplifiers series. Designed for industrial automation racks, the board translates command voltages from a motion controller into regulated current for proportional hydraulic valves, allowing closed-loop position or pressure control in hydraulic axes. It is intended for electrohydraulic control loops where stable valve drive and compact rack installation are both required. By converting low-level control signals into valve-driving current, the amplifier supports precise hydraulic motion without requiring a separate external signal-conditioning stage.
Physically, the amplifier follows the Eurocard outline with a board area of 100 x 160 mm. Connection to the backplane is made through a DIN-style header with 32 connector pins, which separates power, reference, and monitor lines to reduce crosstalk. The control electronics consume less than 200 mA, which helps keep heat generation low when several cards share the same supply rail. A local regulator provides an analog rail of ±15 V for the operational amplifiers, while external logic and relay drivers operate from a symmetric bus of ±24 V. This layout helps keep analog references cleaner in mixed-signal racks where multiple cards operate side by side. The 8 HP aluminum front plate spans 128 mm in height, so the module fits standard IEC 60297 subracks without special hardware.
Dynamic valve actuation is improved by the built-in dither generator set to 340 Hz, a frequency that helps overcome spool friction without creating audible noise. The current ripple is limited to 3 mAPP, which helps prevent unnecessary heating while maintaining a clean hysteresis breakaway. An onboard relay with a switching window of 1 ms can disable the power stage when a fault is detected, and its coil presents a resistance of 2000 Ω so the logic circuitry draws only modest additional current. Three PID potentiometers on the faceplate allow adjustment of proportional, integral, and derivative gains, and the installed voltage regulator helps keep those settings stable against supply fluctuations. This arrangement allows the response of the connected hydraulic axis to be matched more closely to cylinder dynamics and load changes.
