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.

Power Supply Voltage/Current

Values

Power Supply In (V+)

3.7A†

IO-Link Connectors Ports 1-8

C/Q

L+

Maximum

200mA

IO-Link Master Power

155mA @24VDC (Vs)

Note

The total supply of current for all connected IO-Link devices.

IOLM DR-8-EIP-T 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-EIP-T to a power supply.

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

Insert positive and negative wires (12-24AWG) into the V+ and V- contacts.
Tighten the wire-clamp screws to prevent the wires from coming loose.
Apply the power and verify that the following LEDs are lit indicating that you are ready to begin configuration.
- PWR
- MOD, during the power-on sequence, this LED is lit. After power-on, one of the following occurs:
  - The green LED is flashing to indicate that it is in standby mode.
  - The green LED is lit to indicate that it is operational.
- NET, during the power-on sequence the LED is lit. After power-on, one of the following occurs:
  - Off indicates there is no IP address
  - Steady red indicates duplicate IP address on the network
- The Link LEDs should be steady green indicating that the link is up. The ACT LED flashes to indicate network activity.
