Page 5: Introduction
Platinum software. The DCR100 easily handles resistive DC loads like lights, or inductive DC loads like pumps and motors. The DCR100 can also be used to switch AC circuits using external relays. An added benefit of the DCR100 is that it reports the current through each of the six channels. -

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. -

Connector Face Views 2.4.2 Switched Power Connections The DCR100 switched power connections are made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the four screws at the corners of the unit detaching the splash guard from the unit. -

This fuse or circuit breaker must be sized to be no larger than 10A. For example, if you are using all six channels of the DCR100, there must be 6 circuit breakers and a separate power lead from each circuit breaker to the Px terminal for each channel. -

“Troubleshooting”. 2.5 Configuring the DCR100 The DCR100 will transmit data over the NMEA 2000 network as it is shipped from the factory; however, it may require configuration, depending on the type of switch monitored. There are several configurable items within the DCR100, which are detailed in the remainder of this section. -

2.5.4 Switch Control This menu allows you to see the current state of each switch on the DCR100 (“On”, “Off”, or “Error”). It also allows you to set each switch to the ON or OFF state. Setting the switch to the Off State will clear an Error condition. - Page 12 • Ensure that the DCR100 has the appropriate NMEA 2000 ® PGNs enabled as described in Section 2.5.1.1. A breaker/switch always The DCR100 may have shut down the affected channel due to an reads “Error” overtemperature or overcurrent condition detected on the DCR100 relay itself.

Periodic Data Transmitted PGNs PGN 127501 – Binary Switch Bank Status The DCR100 uses this PGN to transmit the state of each of the connected switch inputs Field 1: Indicator Bank Instance – This field identifies the particular switch bank to which this PGN applies. - Page 18 6: Relay Current – This field indicates the current flowing through the relay channel in units of 0.1A. 7: Reserved – This field is reserved by Maretron; therefore, this field always contains a value of 0xFFFF (the DCR100 sets all reserved bits to a logic 1).
