Rexroth Hydraulics MDC1-16 Controller

The Rexroth Hydraulics MDC1‑16 is a mobile electronic controller used to drive hydraulic cylinders and motors in industrial machines. Common failure modes for this unit include power supply board faults (over‑voltage or capacitor leakage), I/O module degradation (corroded contacts or burnt pins), and firmware corruption that triggers “communication lost” or “parameter error” messages. Initial diagnostics should verify the 24 VDC/48 VDC input voltage, inspect the main PCB for burn marks or swollen capacitors, and read any stored error codes via the controller’s diagnostic port before proceeding to module replacement or firmware reflash.[oss-gpt-20b]
