More info
The DCU 305 R3 LT is the class-approved Auto-Maskin panel for engines without an electronic CAN bus – the classic mechanical diesel on a generator set, emergency set, fire pump or propulsion engine. It combines the separate monitoring and safety functions the classification societies require in one unit, with a built-in backup of the shutdown channels.
On board it handles
- Start, stop and blackout start in emergency, auxiliary or combined mode
- 12 switch inputs, 5 × 4–20 mA inputs and two magnetic pickups for engine speed
- Every channel set as warning, alarm or shutdown; event log and plain-text alarms on the backlit display
- 4 switch outputs and 2 potential-free relays, Modbus RTU to the ship's alarm system
- Configured from a PC with the Rudolf R3 software
System
A DCU 305 consists of the control panel, the RK-66 terminal card where the engine switches and senders are wired, and the two cables between them. The panel is slim enough for small enclosures and the terminal card mounts on a 35 mm DIN rail. Six extra 4–20 mA channels can be added with the AK-6, extra relays with the MK-14, and up to four DCU 305 units can be shown on one RSP 305 remote panel.
Replacing an older Auto-Maskin panel
The DCU 305 R3 LT is the direct successor of the DCU 305 R2 and the replacement for the old 2217, 2700, 500 and DCU 205 systems. Auto-Maskin re-wiring guides for each of them are included in the downloads below.
Type approved by DNV, Lloyd's Register and Bureau Veritas (Marine Pro 300 certificates in the downloads).
Most units are delivered from stock or at short notice from the manufacturer.
