IOLM DR-8-PNIO Connect the Power

Overview

The IOLM DR-8-PNIO provides two redundant power inputs with screw terminals on the top and bottom of the IOLM DR-8-PNIO.

[Note]
Note

Use either power terminals (top or bottom) but do not use both to supply power to the IOLM DR-8-PNIO.

The following provides power information for the IOLM DR-8-PNIO.

Power Supply Current and Voltage

Maximum EMC protection is provided by a low impedance connection between functional earth, the ground when connected to a ground DIN rail, and protective earth. The following table contains power-related information about the power supply.

IOLM DR-8-PNIO requires a UL listed power supply with an output rating of 24VDC.

Connecting the Power

You can use this procedure to connect the IOLM DR-8-PNIO to a power supply.

[Note]
Note

Power should be disconnected from the power supply before connecting it to the IOLM DR-8-PNIO. Otherwise, your screw driver blade can inadvertently short your terminal connections to the grounded enclosure.

  1. Insert positive and negative wires (12-24AWG) into the V+ and V- contacts. You can refer to the port placement.

  2. Tighten the wire-clamp screws to prevent the wires from coming loose.

  3. Apply the power and verify that the following LEDs are lit indicating that you are ready to begin configuration.

    • PWR - The LED is lit indicating that the IO-Link Master is receiving power.

    • MS - The MS LED is off, which means that the IOLM is operating as expected.

      [Note]
      Note

      If the IOLM DR-8-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.

      [Note]
      Note

      If the IOLM DR-8-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.
