3.4.2 Breaker Connections
The CLMD12 breaker connections are made by connecting to the 12-pin J1 connector. The pin
number on the J1 connector corresponds to a breaker number, which is represented as an
indicator number in the 127501 Binary Status Report message or as a Connection ID in the
127500 Load Controller Connection & State message. The correspondence of the J1 connector
pin number to the channel number is detailed in the table below, along with the maximum current
supported by the channel.
3.4.3 Discrete Input Connections
Connect each discrete input channel to a pin on the J2 connector as shown in the table below.
Each connection may switch between open circuit and system ground or the supply voltage.
