Product Overview
The Auto-Maskin DCU410E stands as the flagship engine control unit in the Marine Pro 400E series, delivering IACS-approved, cyber-secure supervision for every diesel engine from 500 kW gensets to 20 MW propulsion plants. Engineered by Auto-Maskin AS in Norway, the Auto-Maskin DCU410E (part number 1006445) fuses a 5.7-inch sunlight-readable touchscreen with swipe navigation, self-configuring I/O, and browser-based programming to slash commissioning time by 70 % versus PLC-based rivals. At its heart, a 32-bit ARM processor executes programmable logic in 10 ms cycles, auto-detecting up to 32 RIO expansion modules on a two-wire SDU link while broadcasting live data to any smartphone via secure Wi-Fi.
Positioned as the nerve center of fixed-speed emergency generators and variable-speed thruster drives, the Auto-Maskin DCU410E delivers SIL-2 capable shutdowns, pre-lube sequencing, and J1939 CANbus integration for CAT, MTU, MAN, and Wärtsilä engines. Its conformal-coated 3C3 electronics and IP66 front bezel shrug off 95 % RH, 55 °C engine-room heat, and 5g vibration—earning type approval from ABS, DNV, LR, BV, CCS, ClassNK, KR, and RINA. One Ethernet cable transforms any laptop into a full HMI, letting engineers drag-and-drop alarm setpoints, start interlocks, and Modbus TCP mappings without proprietary software. In short, the Auto-Maskin DCU410E turns complex SOLAS and IMO Tier IV compliance into plug-and-play certainty, protecting billion-dollar fleets with forensic event logs and zero-downtime remote diagnostics.

Main Features and Advantages
Self-configuring ecosystem: Plug any RIO 410, 425, or 412 module onto the two-wire SDU link and the Auto-Maskin DCU410E names, scales, and maps every channel in 9 seconds—zero address dip-switches, zero spreadsheet hell.
Cyber-secure by design: IEC 62443-4-2 SL2 certified, with signed firmware, encrypted Wi-Fi (WPA3), and role-based web logins—blocking ransomware that once crippled a Maersk fleet for 11 days.
Browser-based LASAL-class programming: Drag-and-drop ladder, function blocks, and PID loops from any Chrome tab; password-protected “Operator” vs “Superuser” views prevent accidental overspeed trips.
Swipe-to-diagnose touchscreen: Sunlight-readable 500 cd/m² display shows live gauges, trend graphs, and plain-text alarms in 12 languages—crew resolve 85 % of faults without the chief engineer.
Forensic black-box: 10 000-event circular log with 1 ms timestamps streams to VDR or cloud via Modbus TCP—root-cause a lube-oil shutdown in 90 seconds.
Pre-lube & start sequencer: Programmable 0–300 s pre-lube, cranking, and rest cycles with ETR/ETS fuel & air shut-off—extends starter life by 40 % on MAN 48/60 engines.
Zero-downtime hot-swap: Rear connectors stay live while the front bezel lifts off for cleaning—swap a faulty unit during watch change without dropping the clutch.
