Product Description:

The Bosch Rexroth Indramat 0 811 405 079 is a plug-in servo amplifier card positioned within the 1M Servo Amplifier Cards series. Designed for mounting in a 19-inch Eurocard rack, the board provides analog control of proportional or servo-hydraulic valves in industrial motion systems. By converting low-level command signals into regulated solenoid currents, the card enables closed-loop positioning or force control functions commonly required in presses, injection molding machines, and metal-forming equipment.

Electrical supply requirements are straightforward, with a nominal input of 24 V DC powering the internal electronics and output stage. Physical dimensions follow the IEC 60297 format; the card measures 160 mm in depth and 100 mm in height, so it occupies a single Eurocard slot without obstructing adjacent modules. Under maximum load, the board draws 2.5 A, which corresponds to a peak consumption of 60 VA. These values are useful when sizing back-plane power rails and cabinet wiring. The analog architecture expects an external command potentiometer with at least 1 kΩ resistance, and a stabilized +10 V / 20 mA reference is provided for this purpose. One output stage supplies up to 2.5 A to a proportional solenoid, while the 19-inch rack back-plane distributes the supply and command lines.

Integration with the system rack uses the DIN 41612-F32 connector, and the narrow 7 TE front plate leaves room for dense multi-axis assemblies. Dynamic characteristics suit rapid hydraulic actuation; valves reach rated stroke within 50 ms, and inherent hysteresis remains below 4 %, promoting repeatable positioning. The board regulates coil current in analog mode for direct control of a proportional solenoid from the rack-based interface. Total weight is 0.32 kg, which keeps the load on card guides low during installation and operation.
