REXROTH VT11118-11 R900211788
The Bosch Rexroth VT 11118-11 is an analog differential amplifier card designed for controlling proportional valves without electrical position feedback. It is engineered in a standard Eurocard format for seamless integration into 19-inch rack systems. This amplifier processes differential input voltage signals and converts them into a corresponding output current to drive the proportional solenoid. It features adjustable parameters including command value attenuation, bias, and a ramp generator with separately adjustable ramp-up and ramp-down times. The VT 11118-11 is ideal for applications requiring precise control of pilot-operated proportional pressure reducing and relief valves, ensuring reliable and stable performance in hydraulic systems.
