Product Description:

The VT-TSPD-1-20/V0/0 is part of the Bosch Rexroth range of digital amplifiers. It is suited for the control of proportional valves without electrical position feedback, ensuring efficient regulation of hydraulic systems. This amplifier facilitates smooth and responsive valve operation, making it ideal for applications requiring accurate pressure and flow control. It integrates seamlessly into electrohydraulic systems, supporting a wide range of proportional valve functions in manufacturing, process engineering and heavy machinery. This model is designed as a printed circuit board in Europe format, measuring 100 x 160 mm. This compact form factor ensures optimal space utilization, simplifying the integration process.

This amplifier has an upper voltage limit of 30 V and a lower limit of 21 V, allowing for stable operation even in cases of minor voltage fluctuations. This flexibility in voltage tolerance enhances system reliability by preventing performance issues due to slight variations in power supply. The amplifier comes equipped with a 4 A time-lag fuse, which provides essential circuit protection by preventing excessive current from damaging the amplifier. The time-lag ensures that brief power surges do not cause unnecessary interruptions, allowing stable operation.

The VT-TSPD-1-20/V0/0 is equipped with a valve output stage that supports a maximum solenoid current of 2.5 A per solenoid. This provides the necessary power for precise control of larger valves in industrial automation, heavy machinery or automotive systems. The amplifier’s 64-pole male multipoint connector allows for multiple signal connections in a compact form, ensuring high-density wiring with minimal space requirements. This enhances the flexibility of the amplifier in complex systems, making it easier to integrate into various industrial applications. For seamless communication with external devices, the amplifier features a serial interface RS 232 with a D-Sub socket.
