Product Description

Engineering products by Bosch Rexroth are characterized by their high operational reliability and functionality. These state-of-the-art devices cover numerous applications in industries such as drive and motion control and industrial hydraulics. One family of such products is the VT-MSPA valve amplifier series for proportional valves with solenoids.

The VT-MSPA2-2X-A5-1A0-000 is a model of the valve amplifiers in Bosch Rexroth’s VT-MSPA series used for controlling proportional valves without electric position feedback. Like others in this series, it is a compact device with a modular build and is well suited for proportional valves with two solenoids. Its installation is simplified and is done by snapping onto top hat rails at a maximum height of 2000m. The valve amplifier should also be operated with a direct voltage supply of 24V with a tolerance between +40% and -20%. Additionally, it comes with a power supply unit with a making current limiter that supplies all internally required positive and negative supply voltages. Its making current limiter protects it from damage by preventing high making current peaks.

Conductive dust and solid external materials over 12mm cannot penetrate the VT-MSPA2-2X-A5-1A0-000 to cause damage, as indicated by its IP 20 rating according to EN 60529. The valve amplifier’s maximum power and current consumption values are 48W and 2A, respectively. It also has protective features like its short circuit-proof output stage and the reverse polarity protection of its operating voltage. LEDs are present in this model to inform users of the device's operating status in real-time. They are also helpful tools for fault identification and rectification. This electronic unit’s housing is composed of glass-fiber reinforced polyamide plastic, and it displays limited resistance to UV exposure.
