VT-VSPA2-1-21/V0/T1
The Bosch Rexroth Indramat VT-VSPA2-1-21/V0/T1 is a high-performance proportional amplifier from the VT-VSPA Proportional Amplifiers series, designed in a European board format for seamless integration into modular control systems. This amplifier operates with an analog signal type, accepting a single differential input rated at ±10 V, and is compatible with a range of proportional valves including the 4WRA.-2X and the 3DREP6. Its primary function is to regulate both pressure and flow in hydraulic circuits by converting analog command signals into precise control outputs for directional and pressure valves.
Equipped with an internal reference code of R901002090, the VT-VSPA2-1-21/V0/T1 belongs to component series 2X and features an integrated DC/DC generator without a raised zero point. The device supports internal command value inversion via a jumper or 24 V input, and allows fine-tuning of the internal ramp time (default 1 ms) through an external potentiometer. A comprehensive fault recognition system continuously monitors output stage over-current conditions, de-energizing the outputs upon detection of a malfunction. LEDs on the front plate provide clear status indication for operational and fault conditions.
This amplifier requires no switchover between voltage and current inputs, offering uninterrupted performance in demanding industrial environments. It allows independent adjustment of positive and negative maximum command values to match specific hydraulic requirements and stores safely at temperatures ranging from –25 °C to 85 °C. Adhering to Class F design standards, it conforms to DIN 41494 specifications, ensuring robust insulation and thermal endurance. By integrating proportional pressure and directional control with advanced diagnostics and adjustable response characteristics, the VT-VSPA2-1-21/V0/T1 delivers reliable, efficient control for modern industrial automation applications.
