6.2 L-ADIO

The L-ADIO is the standard analog and digital I/O peripheral for low voltage (<60Vdc) systems. The L-ADIO com-
municates on CAN bus to the controller and provides user access to I/O management via the CXC HP controller.
Power Input
6.2.1 Analog Inputs
Four voltage inputs, V1 – V4, are provided for a variety of voltage monitoring requirements. The input channels
can measure a signal between -60Vdc to +60Vdc.
Four current input channels, I1 – I4, provide monitoring of current; e.g., discharge (load) and charge (battery).
The CXC HP is capable of monitoring standard shunts of 25, 50 and 100mV as well as application specifications
of up to 250mV. The shunt current rating can be configured via the controller and is set by default to 800A 25mV.
The input range for this signal is -250mV to +250mV.
Four temperature input channels, T1 – T4, provide monitoring of temperature probes (thermistors). These are typi-
cally used for either ambient temperature, or for battery post monitoring to enable battery temperature compen-
sation. The temperature sensor is provided by Alpha in various lengths. The input range for this signal is 0V to 5V
and is powered internally from the L-ADIO.
6.2.2 Digital Inputs
The L-ADIO can accommodate up to eight digital input channels, D1 – D8. Each channel responds to a zero
or system voltage potential at the input to activate or deactivate the appropriate condition. These channels can
monitor digital alarm/control signals from rectifiers, converters and many other types of equipment. An additional
digital input, "EXT" is reserved for monitoring an external LVD override.
6.2.3 Alarm and Control Output Relays
Each L-ADIO contains twelve Form C alarm output relays to extend alarms and to control external apparatus.
Each internally generated alarm or control signal may be mapped to any one of the 12 relays, several signals may
be mapped to just one relay or none at all.
