====== 804DCL - ES High Power DC Link Box ======

{{:hardwarepub:modules:es-heavy-duty.jpg?direct&400|}}

The High Power DC Link box is designed to provide a centralised point for all primary DC power distribution on small to medium sized vessels.  The system is will take feeds from up to three battery banks (two engine and one domestic), provide a way to isolate the batteries from the rest of the system and provide a range high power fused feeds from both permanent and switched side of the isolators.

===== Key features =====

  * 2x Engine battery isolation and distribution
  * Domestic battery isolation and distribution
  * High power fuses to feed sub-distribution boards
  * Automatic cross charging between battery banks
  * Domestic battery monitoring
  * 500A shunt for domestic battery monitoring
  * Control card for remote power control and monitoring
  * E-Plex monitoring and control

^ Output ^ Type ^ Description ^
| Engine 1 | Digital | This pin will be high whilst the engine 1 isolator is connected. |
| Engine 2 | Digital | This pin will be high whilst the engine 2 isolator is connected. |
| Domestic | Digital | This pin will be high whilst the domestic isolator is connected. |
| Dom - Eng 1 (battery link) | Digital | This pin will be high whilst the domestic and engine 1 batteries are connected. |
| Dom - Eng 2 (battery link) | Digital | This pin will be high whilst the domestic and engine 2 batteries are connected. |
| Dom - Eng 1 (charge activation) | Digital | This pin will be high if the domestic and engine 1 batteries are connected because charging has been detected. |
| Dom - Eng 2 (charge activation) | Digital | This pin will be high if the domestic and engine 2 batteries are connected because charging has been detected. |
| Engine 1 Volts | Analogue (10-bit) | The voltage of the engine 1 battery in deci-Volts (e.g. 175 = 17.5 V). |
| Engine 2 Volts | Analogue (10-bit) | The voltage of the engine 2 battery in deci-Volts (e.g. 175 = 17.5 V). |
| Domestic Volts | Analogue (10-bit) | The voltage of the domestic battery in deci-Volts (e.g. 175 = 17.5 V). |
| Domestic Amps | Analogue (16-bit, signed) | The current flow through the domestic battery in deci-Amps.  32768 = 0 A, 32769 = 0.1 A, 32767 = -0.1 A. |
