Product Description:
The VT-MSPA1-22-A5-000-000 is a single-channel amplifier card produced by Bosch Rexroth Indramat within the VT-MSPA Drives series. It conditions command signals and supplies controlled current to proportional solenoid valves, so it serves as an interface between low-level control electronics and hydraulic actuators in industrial automation cells. By generating a regulated output current in response to a voltage command, the module enables precise pressure or flow adjustment without the need for separate discrete components.
Input power parameters determine cabinet design and protective wiring. The module operates from a nominal bus of 24 V DC, yet it remains functional between 18 V and 36 V. Under steady load the card draws less than 2 A, translating to a thermal demand below 48 W. A 3.15 A time-lag fuse on the supply line prevents sustained overcurrent, while switch-on inrush stays under 4 A. To keep valve dither free from noise, residual ripple on the internal rail is limited to 2.5 Vpp. The command input presents 200 kΩ of resistance, allowing direct connection to PLC analog outputs, and the load circuit must not fall below 1000 Ω to preserve current linearity.
The output stage and enclosure protection show the card’s operating limits. The card can deliver up to 2.7 A of controlled current to a solenoid, which covers most NG6 and NG10 proportional valves. The maximum command voltage accepted on the reference pin is +10 V, giving full-span modulation for common 0 to 10 V control schemes. Installation inside a control cabinet is expected because the housing has an IP 20 protection class, so it resists touch but not water spray. After power is applied, the circuitry reaches a stable state in less than 1 s. With a mass of only 0.14 kg, the board adds minimal load to DIN rail structures.
