Product Description:
The VT-VSPA1-1-1X-002-30SEC is a plug-in proportional amplifier card from Bosch Rexroth Indramat in the VT-VSPA Proportional Amplifiers series. The unit mounts as a 100 mm × 160 mm Eurocard and interfaces with valve coils through a single rack connector. In industrial automation, it translates low-power command voltages from a controller into controlled solenoid current, allowing hydraulic proportional valves to follow precise reference signals for pressure and flow regulation on presses, plastic machines, and general motion axes.
The amplifier operates from a nominal system voltage of 24 VDC and remains functional until the supply drops to +22 V or rises to a ceiling of +35 V. Within this span, its internal circuits draw up to 1.8 A, translating to a peak power demand of 50 VA under worst-case loading. These limits set the power budget that must be allocated on the machine’s low-voltage rail and help determine suitable protective devices and wiring sizes. A slow-blow fuse can be installed in line with the card, and its front plate also carries status LEDs for quick diagnostic reference while the 32-pole DIN 41612 backplane connector streamlines installation.
Signal handling features include a command input resistance of 100 Ω, enabling direct interface with PLC analog outputs without excessive loading. The actual value channel uses a scaling of 1 mV/mA, so a 100 mA spool current appears as 100 mV for monitoring or feedback loops. Output driver circuitry can source or sink ±25 mA, allowing control of most NG6 and NG10 proportional solenoids while remaining below the onboard protective fuse rating of 2.5 A with a slow-blow characteristic. The module also conforms to the 100 × 160 mm outline, carries a front-plate height of 128.4 mm, provides a reference voltage of ±9 V for sensor circuits, and, at 0.1 kg, adds minimal mass to the rack.
