Product Description:

The VT-MSPA2-1-10-V0-0 is an amplifier card manufactured by Bosch Rexroth Indramat for the VT-MSPA Drives series. It converts low-level command voltages into controlled solenoid current so that proportional hydraulic valves can be driven directly from automation controllers. By placing the electronics on a DIN rail inside the control cabinet, the card separates signal processing from the harsh hydraulic environment and simplifies field wiring. As part of a closed-loop motion or pressure circuit, it provides fine adjustment of oil flow, enabling precise positioning, clamping, or speed regulation on presses, injection molding machines, and material handling systems.

The board presents 12 spring-type terminals that accept supply, command, and solenoid leads, keeping installation tool-free. Its analog output stage is rated for a minimum load of 1000 Ω, preventing distortion when driving feedback meters or PLC inputs. Supply protection is handled externally with a 3.15 A time-lag fuse that tolerates brief inrush events. During steady operation, the module draws < 2 A, and its internal regulators limit residual ripple on the output to 2.5 Vpp, maintaining valve stability. The controlled channel can deliver up to 2.7 A to the solenoid, which is suitable for most NG6 and NG10 proportional valves. An enclosure classification of IP20 indicates finger-safe terminals but requires mounting inside a protected cabinet.

Power to the card is normally taken from a control bus; the permissible range spans 18 V minimum to 36 V maximum, and initial energization draws less than 4 A. Once powered, the circuitry settles in < 1 s, and full functionality is available. Typical energy demand is below 48 W, so cabinet thermal load stays low. Output zero can be trimmed within ±10% to compensate for valve offset. With a nominal input of 24 V, the amplifier supports standard control power systems, and its total mass of 0.14 kg keeps the module light enough for DIN-rail mounting without additional supports.
