Product Description:

The VT-MSPA1-200-1X-V0-0 is a proportional amplifier card produced by Bosch Rexroth Indramat within the VT-MSPA Drives series. Designed for DIN top-hat rail installation, the card converts low-level control signals into current-controlled outputs for one hydraulic solenoid, ensuring repeatable valve positioning in automated presses, test rigs, and assembly lines. By integrating power conversion, overload protection, and diagnostic indication on a 25 mm wide module, it eliminates separate boards and simplifies cabinet wiring in distributed motion-control systems.

The electronics operate from a nominal supply of 24 VDC; the internal regulators remain functional down to 21 V and tolerate line excursions up to 35 V without damage. Under worst-case loading, the module draws less than 1.3 A and dissipates under 50 VA. A peak solenoid drive of 1.0 A is available, optimized for coils with 8.3 Ω cold resistance so that the valve reaches rated force while staying within thermal limits. An electronic overload monitor and an onboard SMD fuse disconnect the output if the current rises unexpectedly. The front-panel measuring socket follows a scale of 1 mV per 1 mA, allowing a multimeter to verify coil current without breaking the circuit.

Control inputs present a high-impedance path of 100 kΩ, minimizing load on PLC analog cards. Wiring is completed through six screw terminals, and a green LED shows ready status once the logic rails settle. The plastic housing measures 25 x 79 x 85.5 mm and fits directly onto a 35 mm top-hat rail, leaving adjacent slots free for additional cards. With a protection rating of IP20, the module is intended for closed electrical enclosures where touch safety rather than liquid sealing is required. The assembly weighs just 0.15 kg, which helps reduce handling effort in densely packed control cabinets.
