InteliDrive DCU Marine - 3.0.0 Global Guide
57
Fuse value and type depends on number of connected devices and wire length.
Recommended fuse (not fast) type - due to internal capacitors charging during power up.
Power supply
Use min. power supply cable of 1.5 mm2 to ensure proper function.
Maximum continuous DC power supply voltage is 36VDC.
Maximum allowable power supply voltage is 39VDC – see chapter Technical data.
Note: For redundancy power supply use ID-RPU module – see chapter Recommended wiring.
Note:
The InteliDrive DCU Marine controller should be grounded properly in order to protect against atmospheric
discharges!
Install separate conductors for signal and power inputs. Allow for conductor voltage drop when determining
conductor size. All power supplies must have common ground.
When there is a potential risk of the controller being subjected to conditions outside its capabilities - an outside
protection device should be used.
4.3.2 Analog as Binary input
To use Analog input as binary configure following characteristics:
Primary Converted
0 0
1000 1
4.3.3 Analog as three state (tristate) binary input
Open, close and failure (broken wire, short wire) states are detected. Threshold level is 750 Ω, failure is
detected when circuit resistance is <10 Ω or > 2400 Ω
