4.3 HV ADIO
The HV-ADIO is the standard analog and digital I/O peripheral for high voltage (>60 to <300Vdc)
systems. The HV-ADIO communicates on CAN bus to the controller and provides user access to I/O
management via the CXC HP controller.

See the customer connections drawing (xxx-08) at the rear of this manual for additional information on
the HV-ADIO.
4.3.1 Analog Inputs
Two voltage inputs, V1 – V2, are provided on the HV-ADIO for a variety of voltage monitoring require-
ments. The input channels can measure a signal between -300Vdc and +300Vdc.
One current input channel, I1, provides 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 appli-
cations specifications of up to 200mV. The shunt current rating can be configured in the Controller user
interface and is set by default to 800A 25mV. The input range for this signal is -200mV to +200mV.
Two temperature input channels, T1 – T2, provide monitoring of temperature probes (thermistors).
These are typically used for either ambient temperature, or for battery post monitoring to enable battery
temperature compensation. 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 HV-ADIO.
Two DCCT inputs, DCCT1-DCCT2, are provided on the HV-ADIO. The input range for this signal is ±4V
or ±10V for additional current measurements using isolated fall effect type sensors. Two sensor ranges
are supplied by Alpha 4V and 10V. The sensors are powered by the ADIO using and internal +15V
isolated power supply.
4.3.2 Digital Inputs
The HV-ADIO can accommodate up to four digital input channels, D1 – D4. Each channel responds to
contact closure 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.
WARNING: Do not connect voltage to these inputs, they function differently than the digital OP on the
L-ADIO.
