thermocouples, RTD (Pt100)
all measurement modes individually
isolated
CANSAS-HCI8, by means of its 8 isolated channels, enables the measurement of: voltage, current,
resistance and temperature.
Highligths:
isolated measurement of low voltages, resistor, current and temperature (thermocouples and
Pt100) on a high common mode level
differential: max. 60 V measurement range / 600 V overvoltage protection at 800 V common mode
isolation
high signal bandwidth
typical applications for the module include on board hybrid vehicles and measurements of battery
and fuel cells etc.
It supports the CANopen protocol according "CiA DS 301 V4.0.2" and "CiA DS 404V1.2"; 4 TPDO
(Transmit Process Data Objects) in INT16, INT32, and FLOAT. The supported capabilities, more
standards and the settings which can be edited via CANopen are described in "CANSAS
CANopen ". CANopen mode does not support virtual channels and controlling the LEDs.
Technical details of the HCI8 .
6.14.1 Voltage measurement
configuration for voltage measurement
Voltage:
±20 mV to ±60 V
The differential input impedance is
6.7 M in ranges up to ±2 V. For all
other ranges and if the device is
de-activated, the impedance is
always 1 M .
The inputs are DC-coupled. The
differential response is achieved by
means of the isolated circuiting.
