Product Description:
The VT-MSPA2-21-F5-000-000 is an electronic drive card manufactured by Bosch Rexroth Indramat within the VT-MSPA Drives series. Designed for industrial automation, the card converts low-level current command signals into regulated power for proportional solenoid actuators. This allows precise positioning and pressure control in hydraulic systems. Its control behavior suits valve applications that require stable current regulation during changing load conditions.
The card accepts a command current between 4 mA and 20 mA; this range lets standard 4–20 mA transmitters drive the module without scaling. The differential input presents 100 Ω of resistance, so the transmitter sees a predictable load while still delivering enough compliance voltage. Downstream of the input, the electronics draw < 2 A during continuous operation and consume < 48 W, reducing enclosure heat. For protection, a 3.15 A time-lag fuse is used on the supply line, and the inrush at power-up stays below 4 A. The output stage can feed the connected valve while maintaining a residual ripple of 2.5 Vpp, and it tolerates load impedances down to 1000 Ω without instability.
The solenoid channel supplies up to 2.7 A of controlled current, giving headroom for medium-force proportional valves. Supply rails can vary from 18 V to 36 V, yet the control circuitry is optimized around a nominal 24 V level to keep the output linear and limit dissipation. Start-up current peaks are limited so that external wiring sized for the continuous rating remains adequate. Environmental protection corresponds to the board-mounted IP20 class, meaning the card is finger-safe but not sealed against dust ingress, so it is normally installed inside a cabinet. This protected mounting arrangement helps keep airborne contamination away from the open card assembly during operation.
