2.3.6
Analog Input Channels
The CXCI/CXCI+ has analog input channels for voltage, current, and temperature.
2.3.6.1
Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage.
The CXCI/CXCI+ software is pre-configured to monitor V2 for load and for battery voltage. V2 is
used as the system reference for converter float voltage, low voltage disconnect (LVD), system
high voltage alarm, and system low voltage alarm. V1 is available for additional measurements.
2.3.6.2
Current Inputs
The CXCI/CXCI+ software is pre-configured to monitor I1 for load current using an external
50mV current shunt.
2.3.6.3
Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and
temperature compensation (temp comp) or room/ambient temperature. A voltage is supplied to
these terminals to power the temperature sensors.
2.3.7
Digital Input Channels
The CXCI/CXCI+ has digital input channels to monitor alarm/control signals from converters, rectifiers, and many
other types of equipment.
2.3.8
Alarm and Control Output Relays
The CXCI/CXCI+ contains Form C digital alarm output relays to extend alarms and control external apparatus.
Each internally generated alarm or control signal may be mapped to any one of the relays, or, several signals may
be mapped to just one relay or none at all.
2.3.9
Network Connection and Remote Communications
The Cordex system can be set up, monitored and tested via Ethernet 10/100 Base-T serial data connection. The
communication protocol supports a web interface. All alarming and control of Cordex converters is accomplished
with a CXCI/CXCI+ via a CAN bus.

Cordex 24-48/2kW Converter
The Cordex converter modules plug into the Cordex converter shelf. The modules can be installed or removed
from a system without disturbing the system provided sufficient current capacity remains. This is often referred to
as “Hot Swap.”
The total output current capacity of the converter system is equal to the sum of the individual current capacities of
the converter modules.
