3 Product Description
The JXM-IO-E31 expansion module is a universal building block for remote I/Os
on self-propelled machines. With its balanced I/O configuration, it can handle al-
most all remote tasks and is particularly suitable for controlling brushed DC mo-
tors in self-propelled machines.
Communication with the JXM-IO-E31 takes place via CANopen. This allows for
integration into conventional CAN networks used in self-propelled machines.

Half-bridge outputs
All half-bridge drivers have a Hall effect sensor for more accurate current mea-
surement.
INFO Restriction
The 12A half-bridges require the half-bridges1 and2, as well as3 and4, to
each operate at the same frequency. The frequency can thus be set separately
for each full bridge. This does not apply to 5A half-bridges. Here, each half
bridge can be set separately.
In order to achieve double current carrying capacity, selected outputs can be con-
nected in parallel.

Jetter AG Technical specifications | 4
User Manual – JXM-IO-E31 15 / 68
Example:
If pin PWMi_HL5_1 is configured to PWMO_HB10, then pin PWMi_HL5_ 2 is au-
tomatically allocated and outputs the same signal as PWMi_HL5_1.
This configuration is possible for the following pins:
■PWMi_HL5_1 (allocated PWMi_HL5_2)
■PWMi_HL5_3 (allocated PWMi_HL5_4)
■PWMi_HL12_1 (allocated PWMi_HL12_2)
■PWMi_HL12_3 (allocated PWMi_HL12_4)
INFO Half-bridge maximum starting current
Each half-bridge is designed to support starting currents of up to 50A. 2 parallel
connected half-bridges are designed to support starting currents of up to 100A.
Current levels exceeding the maximum will be detected as short circuit resulting
in all 8 half-bridges being switched off for 10seconds allowing them to cool
down.

4.6.1 Current diagnostics at the outputs
The limit values vary for each output (see Ausgänge [}14]).
All outputs are calibrated at the factory to achieve the highest possible accuracy.
For low current values the current measurement is not linear. The measurement
is therefore linearized by the firmware:
T1 T2

B
Fig.4: Graph: Principle of linearization
ACurrent value
BADC value
■T1 is 200mA. Current below this value is displayed as 0.
■T2 is 500mA. From 200mA to 500mA the measured current value is lin-
earized.
4.6.2 Overcurrent trip at outputs
If overcurrent flows through an output for 500 ms (default value), the overcurrent
shutdown becomes active. This value can be changed using the parameter
OVERCURRENT_TIME. If an overcurrent event is detected, the output shuts
down and the overcurrent bit is set for 10 seconds. During this time the port can-
not be switched on again.
Re-enabling the
port
üThe JXM-IO-E31 is in the Operational state.
ü10s have passed since the output was shut down.
►Set the output value (digital or PWM) of the respective port again.

4.7 Inputs
Within the operating voltage range, all inputs are voltage-proof and overcurrent
protected. The JXM-IO-E31 has 2 separate VEXT_SEN connector pins which
should be used to supply the sensors. The connector pins output the battery volt-
age via a PTC thermistor. The output voltage can be read back in the device so
that a failure of the sensor supply can be detected.
Alternatively, the analog inputs can also be used as digital inputs (DI_PNP).
In addition to the six analog inputs, there is one analog PT1000 input
(AI_PT1000) for using a PT1000 temperature sensor.

Configuration
inputs
Configuration inputs are tristate inputs and are used to set the node ID. The base
address can be set by the user and has the default value 0x40. The node ID can
be shifted by connecting the configuration inputs with VBAT_ECU or GND via an
offset.

WARNING
Risk of burns
Contact with hot surface may cause burns.
►Take protective measures to prevent inadvertent contact
with the device.
►Allow the device to cool down for some time before you
start working on it.
NOTICE
Damages to material or functional impairment due to
welding
Welding on the chassis may damage the device material, or
impair device functions.
►Before you start welding, disconnect all connections be-
tween the device and the electric system of the vehicle.
►Protect the device from flying sparks and welding beads
(splatter).
►Do not touch the device with the welding electrode or
earth clamp.
NOTICE
Dirt and moisture can affect the electrical connections.
►Protect unused pins using blanking plugs.
►Protect all electrical connections with appropriate single
wire seals.
►Clean the area around a connector prior to removing the
mating connector.
NOTICE
Functional impairment due to magnets or motors with
coil
Using magnets or motors with a coil in the vicinity of the
JXM-IO-E31 may adversely affect current readings of the in-
puts and outputs.
►Ensure that there is sufficient clearance or shield the
JXM-IO-E31.
