2.4 Analog Input Channels
2.4.1 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
rectifier float voltage, low voltage disconnect (LVD), system high voltage alarm, and system low voltage alarm. V1
is available for additional voltage measurements.
2.4.2 Current Input
The CXCI/CXCI+ software is pre-configured to monitor I1 for load current using an external 100A/50mV current
shunt in the negative lead.
2.4.3 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.
2.5 Digital Input Channels
The CXCI/CXCI+ can accommodate up to two channels and can monitor digital alarm/control signals from
converters, rectifiers, and many other types of equipment.
2.6 Alarm and Control Output Relays
The CXCI/CXCI+ contains four (4) 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.
2.7 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 CXC via a CAN bus.
