VT-VSPA2-50-10/T5

The Bosch Rexroth Indramat VT-VSPA2-50-10/T5 amplifier from the VT-VSPA Proportional Amplifiers series delivers precise proportional control for hydraulic valve applications. Designed and manufactured by Bosch Rexroth Indramat, this electrical valve amplifier supports proportional pressure control valves and pilot-operated directional valves without electrical position feedback. It features built-in reverse polarity protection for the voltage supply and an integrated step function generator to produce four independent command values via front-panel potentiometers. A dedicated enable input and status LEDs simplify diagnostics and commissioning during machine setup.

This amplifier operates on a nominal 24V supply (range 18–35V), drawing less than 1.2A of current consumption and under 30VA of power consumption at full load. The on-board 2.5AT fuse protects against overcurrent, while multiple Light Emitting Diodes (LED) indicate command call-ups, enable status, and fault conditions. With a clock frequency of 220Hz, the device achieves rapid response, and its ramp time of 30ms to 1s allows smooth valve actuation. The module’s permissible operating temperature range of 0 to 50°C and compact 32-pin male multipoint connector interface enable integration into confined control cabinets. The total weight of 0.13kg minimizes added mass on mobile or space-constrained platforms.

Built for seamless integration into OEM control loops, the VT-VSPA2-50-10/T5 provides reliable, repeatable performance under demanding industrial conditions. Its reinforced protection features guard against supply faults and environmental stresses, reducing downtime and maintenance. Ideal for machining, mobile hydraulics, and automated production lines, this amplifier ensures precise, stable valve positioning and long-term operational reliability.
