The SYDFEE-2X/140R-PSD62K02-0000-A0A1VXX belongs to the SYD Hydraulic Control Systems series from Bosch Rexroth and functions as an electrohydraulic regulator for automated pump control. It runs on a 24 VDC supply and tolerates short-term excursions down to 21 V or up to 35 V so line transients do not interrupt operation. The command interface presents a 100 Ω load, making it compatible with common drive modules, and the electronics draw 0.6 A during steady regulation while allowing peaks of 1.25 A for rapid actuator shifts. Machine wiring terminates on a 12-pole X1 central connector that streamlines replacement. A sealed housing rated IP65 blocks dust and water jets, and the assembly performs reliably between 0 °C and 60 °C for use in typical hydraulic power units.
The controller governs system pressure up to 280 bar yet remains responsive down to 20 bar when no preload valve is installed, giving designers a broad working range. Pressure tracking shows a linearity error no greater than 1.5 %, and the swashplate swivel angle follows commands within 1.0 % for consistent flow adjustment. Hysteresis is held below 0.2 %, preventing lost motion when reversing direction. Control stability is maintained at pump speeds as low as 250 rpm, so low-demand cycles do not cause dropout. These limits combine to deliver accurate pressure and displacement regulation across the entire operating envelope.
