3 Product description
The JXM-IO-E32 is a CAN device with digital inputs for a wide range of pulse
measurements and analog inputs for current, voltage and temperature measure-
ment. One pin with supply voltage and ground reference is added to each of the
ten analog inputs reducing the cabling effort to a minimum. Thanks to three ana-
log outputs (current and voltage) additional applications can be implemented.

4.6 Inputs
Within the operating voltage range, all inputs are voltage-proof and overcurrent
protected. Alternatively, the analog inputs can also be used as digital inputs (DI).
The JXM-IO-E32 has 8 separate VEXT_SEN pins and 2 separate VREF_10 pins
that should be used to power the sensors. Each sensor supply is output via a
PTC thermistor so that a voltage dip caused by a short circuit can be detected.
VREF_10V supplies a stabilized 10 V voltage, while VEXT_SEN outputs the bat-
tery voltage.

WARNING CAN line - Interferences
Faulty communication due to unshielded CAN lines resulting in extreme cases in
personal injury due to malfunction of the device.
►Connect termination resistors of 120 ohms at both ends of the CAN bus.
►Alternatively wire the internal terminating resistor (see Pin assignment).
NOTICE Improving electromagnetic compatibility
Improper implementation of the wiring harness may impair electromagnetic com-
patibility.
►Keep the cables as short as possible.
►Lay power lines and signal lines separated from each other.
NOTICE Damages to material or functional impairment
Improper implementation of the wiring harness may cause mechanical stress.
►Protect the cables from bending, twisting or chafing.
►Install strain reliefs for the connecting cables.
NOTICE Surges resulting from missing protection or fusing
Surges may cause malfunctions or damage to the product.
►Protect the voltage inputs from surges according to the requirements.
►Ensure that the device is handled in accordance with ESD regulations.
NOTICE Incorrect measurement due to differences in potential
Wiring only from sensor signal to device and from supply voltage to battery can
lead to incorrect measurements due to differences in potential.
►For accurate analog measurements, the sensor supply, sensor signal and
sensor ground must be wired together in a star configuration from the device
to the sensor.
