Information About 0811405076

The 0811405076 is a Bosch Rexroth 2X Series analog amplifier card developed for proportional hydraulic valve control in industrial automation systems. It is manufactured in the European-format printed circuit card design and is intended for installation in a compatible card holder or 19-inch rack within electrical control cabinets. The amplifier is specifically designed for Bosch Rexroth 4WRL 10...35 E/W...S-3X proportional directional control valves with electrical position feedback, providing closed-loop control through analog command signals. Its optimized control electronics enable precise valve positioning, rapid commissioning, and reliable hydraulic system performance for machine tools, presses, and industrial motion control equipment.

Key Features:

• Analog Valve Control: Provides closed-loop analog control for proportional hydraulic valves with electrical feedback.
• 2X Series Design: Built as part of the Bosch Rexroth 2X Series with consistent electrical interfaces and technical specifications.
• Euro-Card Format: Uses a standard European-format printed circuit board for cabinet installation.
• Valve Compatibility: Designed for 4WRL 10...35 E/W...S-3X proportional directional control valves.
• 24 VDC Operation: Powered from a nominal 24 VDC industrial control supply.
• High Output Capability: Delivers up to 2.7 A solenoid output current for valve actuation.
• PID Regulation: Incorporates optimized PID control for stable positioning and accurate hydraulic response.
• Standard Electrical Connection: Utilizes a 32-pin DIN 41612 Form F connector for compatible card holders.

The 0811405076 delivers the reliability and precision required for closed-loop proportional hydraulic valve control in industrial automation systems.
