Product Description:
The VT-MSPA2-2X-A5-000-000 is an analog amplifier card developed by Bosch Rexroth Indramat for proportional solenoid control and belongs to the VT-MSPA Drives series. Mounted in a standard DIN carrier, the module translates a voltage reference from a PLC or joystick into a regulated coil current so that hydraulic valves follow the desired position or flow profile. By adding dynamic gain and dither, the card enables smooth motion in presses, injection machines, and general automation where precise hydraulic actuation is required. This behavior helps proportional valves respond more consistently at low command levels and reduces hesitation during small position changes.
The amplifier operates from a nominal supply of 24 V, with a permitted range between 18 V and 36 V, so SELV power supplies can feed the electronics without extra conditioning. Its input stage accepts a control reference of ±10 V, and a differential input resistance of 200 kOhm minimizes loading on upstream analog outputs. During normal operation, the electronics draw no more than 2 A, and power conversion stays below 48 W, limiting heat buildup inside the enclosure. Overcurrent peaks are handled by a 3.15 A time-lag fuse, while switch-on transients of up to 4 A are tolerated without nuisance trips. A residual ripple ceiling of 2.5 Vpp helps keep supply noise from disturbing the coil loop, and the output stage remains safe when the connected impedance stays above the 1000 Ω minimum.
Its output driver can supply a regulated coil current up to 2.7 A, allowing direct connection to most NG6 and NG10 proportional valves without external boosters. The open-frame IP20 protection class requires installation in a clean control cabinet, and operation below a maximum altitude of 2000 m helps maintain dielectric spacing. The hardware weighs only 0.14 kg, which reduces load on card guides when multiple amplifier channels are stacked in a rack. This low mass also makes the module easier to handle during installation and routine cabinet work.
