VT-MSPA1-50-1X-V0

The VT-MSPA1-50-1X-V0 amplifier module by Bosch Rexroth Indramat belongs to the acclaimed VT-MSPA Drives series. This compact unit weighs 0.13 kg and operates on a 24 VDC supply voltage, drawing less than 2 A current while supporting up to 50 A power consumption. Designed as an analog amplifier for precise proportional valve control, it excels in applications requiring stable and accurate solenoid actuation.

The VT-MSPA1-50-1X-V0 features a modular design that mounts easily on a top hat rail compliant with EN 60715 and connects via screw terminals for secure installation. It drives a proportional solenoid rated at 2.5 A through a pulsed current output stage that is short-circuit-proof. The built-in clock pulse generator supplies a stable frequency to the output stage, while the ramp generator limits the control variable gradient. A downstream characteristic curve generator ensures consistent ramp times, and the internal command value signal is the sum of the differential input and adjustable zero point offset.

Additional benefits include monitoring of solenoid cables for breaks and short circuits and overcurrent protection, indicated by a flashing green LED in fault conditions. Connections are made through six threaded terminals, and the module measures 25 x 79 x 85.5 millimeters with an IP20 protection rating for cabinet-mounted environments. It operates optimally between 0 to 50 °C ambient temperature and can be stored safely from –20 to 70 °C. Its robust design, precise control features, and protective measures deliver reliable efficiency and durability in demanding industrial applications.
