Product Description:

The VT-MSPA1-30-1X-V0-0 is an electronic drive module manufactured by Bosch Rexroth Indramat and assigned to the VT-MSPA Drives series. It accepts a 24-volt supply and modulates coil current for proportional solenoids, enabling precise actuation of valves, clutches, or other electromagnetic devices used in industrial automation lines. By translating low-power control commands into controlled output current, the unit bridges PLC logic levels to field actuators while remaining compact enough for dense DIN-rail assemblies inside a machine cabinet. This kind of controlled current output is useful when actuator force must change smoothly instead of switching fully on or off.

During operation, the module is supplied with a 24 V control bus and draws less than 2 A in continuous service, with overall demand capped at <48 W. The inrush stays below 4 A, so standard cabinet breakers can remain small. A voltage input resistance of 200 kΩ and a current input load resistance of 100 Ω help isolate upstream analog sources from loading errors. Output regulation limits ripple on the power rail to 2.5 Vpp, which helps maintain stable electromagnetic force. Up to 2.7 A of solenoid current is available once the electronics are ready, typically in <1 s. Field wiring terminates on 12 Spring-Type Terminals that detach as a block for easier handling during installation.

For protection, the supply line must be guarded by a 3.15 A Time-Lag fuse that matches the device’s transient profile. The plastic enclosure carries an IP20 rating, making the unit suitable for dry control cabinets positioned at elevations up to 2000 m. The power stage supports load impedances down to 1000 Ω while keeping ripple within limits, so proportional coils receive uniform current throughout their stroke. Service weight is only 0.14 kg, which supports clip-in mounting and helps spread heat across the board. The low mass also reduces stress on DIN-rail supports when the cabinet is exposed to vibration.
