Alfa Laval EPC-50 IO Board
Alfa Laval EPC-50 IO Board (Part No.3183045486) is the input and output circuit board for Alfa Laval EPC-50 marine purifier and FCM fuel conditioning module control system. This I/O circuit board collects analog and digital sensor signals including oil pressure, temperature, water interface and valve feedback from the separator unit. The I/O circuit board outputs relay and drive signals to control drain valves, feed pumps, steam regulating valves and solenoid actuators according to EPC50 main CPU commands. The I/O circuit board communicates with main controller via RS485 bus, carries channel LED indicators for fault diagnosis and signal status display. The I/O circuit board serves as essential marine automation spare part for Alfa Laval oil purifier control cabinet overhaul and fuel conditioning system retrofit.

This EPC-50 IO Board unit is rack-mounted PCB board, powered by 24VDC marine power supply, IP20 protection class. EPC-50 IO Board features 16 digital inputs and 16 digital outputs, operating temperature -20℃ ~ +60℃, CE and marine type approval. EPC-50 IO Board belongs to discontinued legacy EPC50 control platform, original factory production stopped, only surplus and reconditioned spare stock available. EPC-50 IO Board is widely fitted on tankers, bulk carriers and container ships for lube oil and fuel oil separator automatic control.

As purifier signal interface hardware, this Alfa Laval IO board realizes data exchange between EPC50 main controller and field sensors & actuators, guaranteeing automatic sludge discharging and fuel oil treatment. Alfa Laval EPC50 series spare parts include EPC50 IO boards, main CPU boards, power supply modules, display panels and communication cables for marine purifier automation maintenance. Alfa Laval EPC-50 I/O circuit boards are trusted replacement units for legacy marine oil separator EPC50 control systems.
