Product Description:
The VT-MSPA 1-21-A5-000-000 is a single-channel power amplifier card from the VT-MSPA Drives series manufactured by Bosch Rexroth Indramat. Installed inside control cabinets, the card modulates current for proportional solenoid valves so hydraulic or pneumatic actuators follow analog commands issued by a PLC. By converting low-level setpoint voltages into controlled coil excitation, it supports repeatable pressure or force regulation in presses, molding machines, and automated assembly stations.
The amplifier operates from an input of 24 V DC, and its electronics limit steady consumption to <2 A, keeping 24 V bus capacity within common supply ratings. During modulation, the output stage can furnish up to 2.7 A to the solenoid, which sets the magnetic force available at the connected valve. Overall power draw stays below <48 W, which helps control heat inside sealed enclosures. A residual ripple tolerance of 2.5 Vpp maintains signal fidelity because an internal filter suppresses high-frequency noise. Field wiring may extend 50 m when 1.5 mm² conductors are used, and twelve spring-type terminals permit tool-free hookup. A 3.15 A time-lag external fuse safeguards the feed, vertical installation aids convection cooling, and the board remains suitable for use up to 2000 m altitude while weighing only 0.14 kg.
Regulation is available within <1 s of power-up, and inrush demand is held to <4 A, allowing standard miniature breakers to be used. The command input presents a high impedance of 200 kΩ, so sensor cards are not loaded, while the output stage expects at least 1000 Ω of coil resistance to avoid saturation. Cabinet-grade IP20 protection shields fingers from live parts but requires the unit to be housed in a clean enclosure. Cable length, fuse selection, and installation altitude should stay within the stated limits when the card is mounted with other motion-control modules in the same enclosure.
