Product Description:

The VT1610-31-E1-4WRD10-3X servo amplifier card is produced by Bosch Rexroth Indramat within the VT 1600 Servo Amplifiers series. Designed for closed-loop control of proportional or servo-hydraulic valves, this plug-in module installs in standardized 19-inch racks to provide precise current regulation and signal conditioning for machine axes. By mounting directly beside PLC or motion controllers, the card helps maintain repeatable flow and pressure in presses, test rigs, and general industrial automation systems.

The physical envelope follows DIN 41494 guidelines, giving a card height of 100 mm and a depth of 160 mm. These dimensions allow the board to slide into eurocard sub-racks without additional adapters. A 32-pin rear connector mates with back-plane wiring so that power, command, and feedback lines are engaged simultaneously during insertion. The amplifier draws a bipolar bus of ±24 V for internal logic and stage power, while its onboard regulators derive a secondary rail of ±15 V that feeds sensor circuits and reference networks. Output switching to the field coils is handled through a relay whose coil exhibits 2000 Ω resistance, limiting holding current and reducing thermal load during continuous energization.

Dynamic performance is influenced by the relay response time of 1 ms, permitting rapid cut-in and cutout of valve drive signals without perceptible lag in the hydraulic process. The module endures ambient temperatures from 0 °C up to 50 °C during operation and survives warehouse conditions down to -20 °C and up to 70 °C in storage, helping protect calibration after long transport. A total width of 8 HP keeps rack spacing predictable, while the front plate height of 128 mm aligns with adjacent plug-in units. Mechanical guides allocate seven divisions on the component side and 5.08 mm on the solder side, helping prevent contact damage during service.
