The R901439037 (VT-MSPA2-2X-A5-000-000) is a valve amplifier manufactured by the reputable Bosch Rexroth Indramat. This amplifier controls proportional valves, essential for industrial hydraulic applications, and pump controls that lack electrical feedback. Valuable features of the R901439037 (VT-MSPA2-2X-A5-000-000) model include adjustable valve parameters, convenient push-button optimisation, and an input range of 0 to 10 V. The amplifier also offers reverse polarity protection, accessible measuring sockets for capturing current values, and separate ramp generators for the adjustment of up and down modes. The device is built with an adjustable command value and a characteristic curve generator. Fitted onto top hat rails, it uses three tension spring plug-in connectors for electrical attachments. The R901439037 (VT-MSPA2-2X-A5-000-000) operates on a 24 V voltage and a power consumption under 48 W. An installed 3.15 A time-lag electrical fuse ensures protection of the device's internal circuitry. The compact device, weighing only around 0.14 kg, also boasts a swift startup time of less than a second and can operate in temperatures up to 60°C.
