5. Configure the DCR100 (Section 2.5)
1.4 Theory of Operation
The DCR100 provides the ability to turn on or off DC power to a load circuit using 6
independent, isolated solid state relays. The DCR100 is a solid state relay, not a circuit
protection device. Each channel contains protection against overcurrent, over temperature,
and short circuit. These protections are intended to protect the DCR100, and not the load or
the associated wires. Each power source supplying power to a device which is controlled by
the DCR100 must be individually protected by a circuit breaker. The circuit breaker must be
sized appropriately for the size of the wire from the circuit breaker to the DCR100 and from the
DCR100 to the load device. In addition, the circuit breaker must be no larger than 10A.
Each channel of the DCR100 may be manually switched on or off using any of the following
methods:
1) Maretron's N2KView
2) Maretron's N2KView
for Vessel Monitoring and Control,
3) Maretron's N2KView
Monitoring and Control Indoor Display, or
4) a Maretron DSM250 NMEA 2000
The switches can be monitored and/or controlled through use of the Breaker/Switch
component in the Electrical Distribution category of the Maretron display products listed above.
In addition, the current through each channel may be monitored through the Breaker/Switch
Current component in the Electrical Distribution category of Maretron display products.
2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron DCR100, you should find the following items:
1 – DCR100 – DC Relay Module
1 – Parts Bag containing 4 Stainless Steel Mounting Screws
1 – DCR100 User's Manual
1 – Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
Please consider the following when choosing a mounting location.
1. The DCR100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the DCR100 can be mounted on a horizontal deck,
vertical bulkhead, or upside down if desired.
3. The DCR100 is temperature-rated to 55°C (130°F), so it should be mounted away from
engines or engine rooms where the operating temperature exceeds the specified limit.
