Product Description:

The VT1600S3X1EES43A81845 servo amplifier card is manufactured by Bosch Rexroth Indramat and belongs to the VT 1600 Servo Amplifiers series. The board is used in industrial automation racks to amplify and condition control signals that drive proportional valves or servo actuators. By translating low-power commands from a motion controller into regulated current, the card maintains closed-loop accuracy for position and speed control while fitting the mechanical layout used by the DIN plug-in standard. Its compact footprint supports multiple axes in a limited cabinet depth.

Mechanical format follows DIN 41494; within that outline, the card stands 100 mm high and extends 160 mm deep, allowing straightforward insertion into standardized 3U Eurocard frames. The front plate is 128 mm tall and occupies 8 HP of horizontal space, so adjacent modules can be packed without airflow obstruction. A rear edge connector with 32 pins links the amplifier to the backplane, separating signal, power, and reference grounds to minimize crosstalk. The internal analog sections are powered from an ±15 VDC rail derived locally on the rack; at full operation, the board draws up to 200 mA, so system power budgeting must reserve that current to avoid undervoltage drift.

Primary drive energy reaches the coil stages through an ±24 VDC nominal supply delivered on the same backplane. Each output channel presents a 2000 Ω coil resistance, limiting steady-state current and simplifying thermal management in dense enclosures. During logic switching, the relay matrix changes state within 1 ms, and the associated solid-state switch sources no more than 1 mA, a value that protects delicate feedback lines. For diagnostic points, any connected moving-coil meter must exhibit at least 100 kΩ impedance so that measurement does not load the internal reference network, and the solder-side track width of 5.08 mm maintains creepage distances under that load.
