Bosch Rexroth 0811405061 Proportional Valve Amplifier Module – PL10 Series
When a proportional valve amplifier fails on the production floor, the consequences are immediate and severe: hydraulic axes lose precise position control, CNC machines halt mid-cycle, and injection molding presses produce out-of-tolerance parts. Every minute of unplanned downtime translates directly into scrapped material, missed delivery windows, and escalating maintenance costs. The Bosch Rexroth 0811405061 amplifier module is the critical electronic interface between your control system and proportional valve — without it, closed-loop hydraulic control simply does not exist.
The PL10 series represents Bosch Rexroth’s dedicated line of DIN-rail-mounted proportional valve amplifier cards, engineered for integration into industrial control cabinets alongside PLCs and motion controllers. Part number 0811405061 is a widely deployed variant within this series, trusted across European and Asian manufacturing facilities for its robust signal conditioning, integrated ramp generators, and compatibility with Rexroth 4/3 and 4/2 proportional directional control valves. As one of the most recognized amplifier references in the Rexroth hydraulics ecosystem, it remains a critical spare part for OEM machine builders and end-user maintenance teams worldwide.
