Product Description:
The VT1610-3X-E1-4WRD16-3X is a single-axis servo amplifier card in the VT 1600 Servo Amplifiers series from Bosch Rexroth Indramat. Designed for mounting in a PLC or valve control rack, the board converts low-level command voltages into controlled coil current for proportional hydraulic valves in industrial automation. By fitting into a modular Eurocard cage, it provides closed-loop position or pressure regulation without additional discrete electronics. This arrangement makes the module suitable for compact hydraulic control systems where rack-based integration and stable analog response are required.
The board follows the Eurocard format, so its 100 mm × 160 mm outline slides directly into standardized 19-inch subracks. A differential 0 to ±10 V command signal sets the required valve position, and the reference enters through a DIN 41612 Form D, 32-pole backplane connector that also carries feedback and power lines. Internal analog circuitry converts this voltage to an adjustable output of ±60 mA, which is suitable for most 4WRD series proportional coils, and the same current is shown on the front-panel meter scaled at ±30 divisions for ±60 mA. Built-in dither at 340 Hz / 3 mAss helps prevent spool stiction by superimposing a small AC component on the DC drive. The board itself draws less than 200 mA from the rack supply, which helps limit loading on shared power buses and supports stable operation in multi-card assemblies.
Stable performance depends on clean power, and the amplifier operates from a smoothed rail of ±22 to ±28 V. A relay on the board engages auxiliary machine functions; its coil presents 2000 Ω of resistance, is energized for only 1 ms per switching event, and is rated for the same supply range so it can share the existing power source. An onboard regulator delivers ±15 V to the sensitive analog stages, isolating them from upstream fluctuations and helping preserve control accuracy during changes in rack load. The meter circuit also follows the front-panel scale directly, which allows quick visual confirmation of output behavior during normal machine operation.
