The SYDFEE-2X/140R-PSB12KD5-0487-A2A0FLX belongs to the SYD Hydraulic Control Systems series from Bosch Rexroth and serves as an integrated pump and valve controller for automated hydraulic power units. It is configured with the external supply and regeneration base pump variant, so recovered oil energy is routed back into the circuit to reduce heat generation. A standard A-type control spool establishes baseline metering for versatile industrial applications, and the assembly is driven in a clockwise direction to match common motor shafts. Its folded 90° installation orientation lets designers position the block tight against machine frames where space is limited. Electrical power is supplied at a nominal 24 V DC, with a usable window between 21 V and 35 V to tolerate battery or supply fluctuations. The controller remains lubricated and responsive down to 250 rpm, allowing low-speed start-up without cavitation.
Standard electronics with leakage-oil compensation keep sensor outputs stable when case pressure varies, aiding closed-loop accuracy. The housing carries an IP65 rating, blocking dust and water jets encountered on mobile or outdoor machinery. A G1/4 threaded port simplifies attachment of hoses and diagnostic gauges. System pressure can be monitored up to 315 bar by the integrated transducer, while the hydraulic passages withstand a continuous operating level of 280 bar. During steady operation the electronics draw 0.6 A, but transient events can demand as much as 1.25 A, so conductors must handle short current peaks without excessive voltage drop.
