EAAM057608EN
Engine instruments analogue
inputs
Three inputs for resistive sensors plus one input for measuring and
compensation of the reference potential of their common minus.
Resistance measuring range:
range: 0...1kohm with error < 1%
extended: 0
– 0...3kohm with error < 2%
The three measurement inputs can also be used as digital inputs with
GND activation, with status change voltage if 1.17VDC
Voltage compensation range of the reference point, with
Rsensors=100ohm:
-2.7...+3.5VDC
Analogue inputs
The input T.16 can be configured from parameter to obtain voltage
signals 0..10VDC referred to GND (T.01)
CANBUS Connection
USB 2.0 for non permanent connection to PC (max 6m) only for the
configuration of parameters with program SICES BoardPrg3.
The device is directly supplied by PC and turns on in OFF/RESET
mode when it is connected, with maximum consumption of 250mA
from USB port.
CANBUS Connection
CanBus connection without galvanic isolation with protocol SAEJ1939
and MTU for the connection to ECU engine control. Fix internal
termination of 120ohm
