Internal Product Review
The 0 811 405 101 is a Bosch Rexroth Indramat servo amplifier card engineered for DREB6X valve applications. Operation at 24 VDC with up to 2.7 A solenoid current gives this card strong control authority in hydraulic servo systems. The DIN 41612-F32 connector supports clean integration, and the 35 W maximum power demand keeps the design efficient for cabinet installations.

Product Description:
The 0 811 405 101 is a plug-in servo amplifier card produced by Bosch Rexroth Indramat for the 1M Servo Amplifier Cards series. Designed to drive proportional solenoid valves, it interfaces directly with the DREB6X electrohydraulic valve family. Within an automation cabinet, the card converts low-voltage control signals into the regulated current required by a valve coil, allowing precise hydraulic flow and force control in presses, machine tools, and assembly equipment.
During operation, the board draws a nominal supply of 24 VDC, and its electronics limit steady control-side demand to 1.5 A, keeping cabinet power requirements predictable. Total dissipation does not exceed 35 W, so convection cooling inside a standard rack is usually sufficient. The output stage can deliver up to 2.7 A to the solenoid, matching the 25 W coil rating without saturation. Mechanical integration follows the Eurocard format; the board measures 160 mm long, and a 7 TE front panel provides ready access to test pins and adjustment trimmers. Connection to the backplane is made through a DIN 41612-F32 male connector that carries supply, command, and feedback conductors to the host rack.
Signal processing on the single output stage relies on an internal reference network. The demodulated LVDT feedback from the valve core is excited at 10.2 V RMS and monitored at 7.8 kHz, allowing the card to close its current loop without external transducers. For on-site tuning, a panel potentiometer with a resistance of 1 kΩ is powered by a stabilized 10 V source, so gain and null can be adjusted without loading the control circuit. The card has a board width of 100 mm, and the assembly weighs 0.36 kg, making it suitable for dense multi-axis racks. The card has one output stage, which supports a single DREB6X valve and simplifies channel assignment in modular hydraulic drives.
