Product Description:

The VT1600S3X-E1 plug-in servo amplifier card is manufactured by Bosch Rexroth Indramat for the VT 1600 Servo Amplifiers series. Within hydraulic motion systems, the card converts command signals from a machine controller into regulated coil current that positions proportional valves or other actuators. The card format follows the Eurocard profile so it can be seated in a 19-inch rack alongside pressure, flow, or directional control modules. This layout supports compact integration inside industrial automation cabinets and keeps related control electronics in a single rack assembly.

The Eurocard dimensions are 100 × 160 mm, and the solder side maintains a 5.08 mm track pitch so backplane plugs mate without strain. A DIN 41612 connector with 32 signal and power contacts links the module to the rack. Internally, the amplifier applies a valve-conditioning dither of 340 Hz with a peak value of 3 mApp to help overcome static friction at the valve spool. Command updates occur on a 1 ms cycle, supporting fast response to changing reference values. The analog reference interface accommodates an internal control swing of ±10 V, and a 128 mm front plate includes test jacks for current measurement and a run/ready LED.

The output stage is matched to coils with a resistance of 2000 Ω, letting the card drive small orifices precisely while keeping heat generation low. Typical consumption from the backplane is less than 200 mA, so several amplifier cards can share the same 24 V supply without placing a heavy load on the cabinet power bus. Physically, the board occupies 8 HP in the rack guide rails, and the aluminum shield weighs 0.15 kg. The narrow width leaves room for adjacent modules, and the low mass helps the card fit dense rack layouts.
