Product Description:
The VT1610-S31-1 servo-amplifier card is manufactured by Bosch Rexroth Indramat and belongs to the VT 1600 Servo Amplifiers series. Its function is to translate low-level control signals from a motion controller into the precise coil currents required by proportional or servo valves, allowing hydraulic actuators to follow position or pressure commands in automated machinery. The board fits a 19-inch rack slot and shares the same power bus as adjacent control cards. This arrangement supports compact rack-based hydraulic control systems where multiple functions are grouped in a single enclosure.
The card plugs into a 32-Pole DIN 41612 Form D back-plane connector, so valve, feedback, and supply lines are routed through the rack header rather than individual screw terminals. System power draw stays below <200 mA, which helps limit the load on a shared supply when several cards operate in one rack. Internal dither is factory-set at 340 Hz / 3 mAss; this small AC component reduces valve spool hysteresis and improves positioning repeatability. The mounting format conforms to the Eurocard outline, and the conductor side occupies only one division in the rack, conserving panel space. Command output is limited to ±60 mA, matching the magnet force range of typical Bosch Rexroth proportional valves and helping prevent coil overheating during continuous operation.
The on-board relay that switches enable signals has a coil resistance of 2000 Ω, which helps reduce inrush current and heat generation. Its switching time is 1 ms, allowing fast shutdown or fault isolation when required by the control circuit. For local diagnostics, the front-panel scale shows valve current across ±30 Divisions, providing a direct visual reference during operation. The regulation electronics use a dual supply of ±15 V, ensuring symmetrical headroom for both polarities of the output stage. Electrical feedback from the valve completes the closed loop, and the entire assembly weighs 0.20 kg, which places only a light mechanical load on the rack frame.
