Product Description
The VT-VSPA1-1-11 valve amplifier by Bosch Rexroth is designed to control proportional pressure valves without electrical position feedback. It is suitable for direct and pilot operated systems and utilizes a single solenoid as the actuating element. The amplifier ensures efficient management of hydraulic systems requiring adjustable pressure control with precise control.
The VT-VSPA1-1-11 operates with a 24 V DC supply accepting a range of input command signals including 0 to 10 V or 4 to 20 mA. It supports both direct and differential inputs that allow adaptability in various control configurations. The amplifier has a maximum power consumption of 50 VA and a maximum current consumption of 1.8 A. The model integrates a fuse rated at 2.5 A for protection. Outputs include solenoid currents adjustable between 800 mA and 1600 mA. The model offers robust and reliable operation. The device's clock frequency can be set between 100 Hz and 160 Hz for precise solenoid actuation. The model has differential input that is switchable between current and voltage. The valve comes with reverse polarity protection for voltage supply and short circuit protection of the solenoid conductor.
The VT series amplifier uses a 32 pole male multipoint connector for connections and it comes in a compact Euro card format measuring 100 x 160 mm adhering to DIN 41494 standards. It supports operation in temperatures ranging from 0 to 50 degrees C and can be stored between - 25 and + 85 degrees C. The model's overall weight is 0.1 kg that makes it lightweight and easy to integrate into existing hydraulic control systems. This valve amplifier is ideal for ensuring stable and accurate pressure control in industrial hydraulic applications.
