Product Description:

The Bosch Indramat 0 811 405 101 operates as a servo amplifier card for industrial automation. The 1M Servo Amplifier Card series includes this amplifier unit which functions to operate proportional valves.

The 0 811 405 101 servo amplifier generates a 10.2 Veff output signal at 7.8 kHz while operating between 0 and +10 V DC values. The amplifier has a 2.5 A peak current capacity and requires nothing more than 60 W power utilization. The solenoid output delivers a pulse-modulated square-wave voltage which supports a maximum solenoid current of 2.7 A at Imax. A signal source for potentiometers having a 1 kΩ resistance enables the input between 0 and +10 V. The PCB package dimension of the amplifier amounts to 100 x 160 x 35 mm. This 0 811 405 101 servo amplifier operates at 24 V DC power supply voltage range between 21 to 24 V. It supports 1.5 mm² cable cross-sections up to 20 meters and 2.5 mm² cross-sections from 20 to 50 meters. To minimize ripple beyond 10% users should use a smoothing capacitor with specifications of 4700 μF and 63 V. The device maintains an assessment of IP40 protection along with a weight measure of approximately 0.25 kg. Adjusting ramp functions is possible through trim potentiometers.

The 0 811 405 101 servo amplifier functions as a critical component for proportional valve control operations in industrial processes. The adaptable ramp configuration enables users to precisely adjust response behaviors. This facilitates tailored performance to meet individual application requirements. Complete performance depends on proper installation which requires following all specified cable standards and power source requirements. The signal processing functionality is embedded in its design which enables efficient modulation of hydraulic systems.
