Figure 1: CMC SNV022EC.ATopology Diagram.
The SNV022EC.A uses the connectors CON1/CON2, CON3/CON4 and CON5/CON6
to connect to the bus and power supply (see table 1).
These connectors are equivalent (terminals are common) and can be used as
bus/power supply input or output to the next card in the chain or install
terminal/bias resistors.
Connector CON7 has two pins to connect a dry contact (switch). The connector
CON7 is used to monitor a switch or a sensor acting as a switch (ex. surge
protection, door opening, disconnector trip etc.).
