The SYDFEE-2X/140R-PSB12KD3-0000-A0A1VXX control module is manufactured by Bosch Rexroth within the SYD Hydraulic Control Systems series to manage proportional valves in hydraulic automation. It operates on 24 VDC with a tolerance of −5 percent to +40 percent, so it connects directly to standard machine supplies. Short-term voltage dips to 21 V or surges to 35 V are tolerated, matching the stated lower and upper limits. Static regulation draws 0.6 A while brief demands can rise to 1.25 A, allowing rapid spool movement. An alpha actual output delivers 1.5 mA for position feedback loops. The analog current input presents a 100 Ω load, and the analog voltage input holds a minimum resistance of 50 kΩ, preventing excessive loading of control electronics.


Digital command lines treat any signal to 0.6 V as low and accept levels from 21 V upward as high, giving clear logic discrimination in noisy environments. The hydraulic circuit can be pressurized to 280 bar without exceeding the unit’s mechanical rating. Continuous service is permitted up to an ambient temperature of 60 °C, and the device withstands storage temperatures to 70 °C. A sealed housing with IP65 protection blocks dust and water jets, supporting installation on the machine frame. A Pactual output also provides 1.5 mA, transmitting live operating data to external monitors. These electrical, thermal, and environmental limits combine to ensure dependable control performance across demanding hydraulic duty cycles.
