IOLM 4-PNIO Connecting the Power
The following provides an installation and
configuration overview for the IOLM 4-PNIO.
IOLM 4-PNIO provides dual M12 (A-coded) power connectors.
|Pin||Input - Male|| ||Output - Female||Comtrol Power Cable|
Green (not used)
Maximum EMC protection is provided by a low impedance connection between functional earth,
the grounding tabs, and protective earth. The following table contains power-related information about the power supply.
Power connectors must have an approved cable or protective cover attached to the port guarantee IP67 compliance.
|Power Supply Voltage/Current||Values|
Power Supply In - Maximum (Us)
C/Q (Pin 4)
Vs (Pins 1 and 3)
Ports 1 -4
200 mA (Maximum)
500 mA (Maximum)
IO-Link Master Power
100mA @ 24VDC (Vs)†
Power Supply Out (Us)
† Us output available is determined by subtracting the following from the available input current.
IO-Link Mode module power
Actual C/Q current for each IO-Link Master port
Actual Vs current for each IO-Link port
You can use this procedure to connect the IOLM 4-PNIO to a power supply.
Securely attach the power cable between the male power connector and the power supply.
Either attach a power cable between the female power connector and another device to
which you want to provide power or securely attach a connector cap to prevent dust or
liquids from getting into the connector.
PWR - The LED is lit indicating that the IO-Link Master is
MS - The MS LED is off, which means that the IOLM is operating as expected.
If the IOLM 4-PNIO has U-Boot bootloader v1.25 or higher, the MS LED is lit during the power-on cycle.
NS - if the NS LED is off;
that means that there is no PLC connected. If the NS LED is lit and green, that
means that a PLC is connected.
If the IOLM 4-PNIO has U-Boot bootloader v1.25 or higher, the NS LED is lit during the power-on cycle.
The Link LEDs should be steady green indicating that the link is up.
The ACT LED flashes to indicate network activity.
