Product Description:
The VT-VSPA2-1-1X-T5 is a plug-in proportional amplifier card manufactured by Bosch Rexroth Indramat for the VT-VSPA Proportional Amplifiers series. It is designed for closed-loop control of hydraulic solenoid valves and converts low-level command signals from a PLC or motion controller into regulated coil current that modulates flow or pressure. By fitting into a standardized 19-inch Eurocard rack, the amplifier provides a compact interface between electronic automation hardware and hydraulic actuators in industrial machinery. It is suited to hydraulic systems that need repeatable proportional control rather than simple on-off valve switching.
The card operates from a 24 VDC supply, and its internal regulator provides the reference rails used for external command voltages. Differential inputs present 100 kΩ of resistance, which helps reduce loading on upstream analog outputs, while four command channels can use a ±9 V span for flexible setpoint scaling. The valve current is limited to a 2.5 A peak, which protects coils with a minimum resistance of 2 Ω and keeps operation within the card’s <50 VA power limit. A 100 Ω burden supports 4–20 mA interfacing, and the enable line must reach 8.5 V before the output stage switches on. These control and protection functions help the amplifier respond predictably to changing command inputs during hydraulic motion.
The Eurocard footprint measures 100 × 160 mm and plugs into the backplane through a 32-pin DIN 41612 Form D connector, which supports straightforward rack installation. Supply protection is provided by a 3.15 AT fuse, and continuous current draw remains below 2 A during normal operation. Auxiliary rails hold ±9 V within 1% for sensor or potentiometer supply, while coil supervision uses a relay with a 2150 Ω winding that trips at 16.8 V to support reliable fault isolation without overstressing drivers. The card weighs only 0.13 kg, so it adds very little load to the rack and leaves room for neighboring cards in dense control assemblies.
