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.6: Graph: Principle of linearization

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-EW30-G27 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-EW30-G27 has 3 separate VEXT_SEN connector pins
which should be used to supply the sensors. The connector pins output the bat-
tery voltage via a PTC thermistor. The output voltage can be read back in the de-
vice so that a failure of the sensor supply can be detected.
Alternatively, the analog inputs can also be used as digital inputs (DI_PNP).
