Digital I/O — This port is configurable as a digital input or

 

digital output and can be used to connect a variety of devices,

 

such as sensors, switches, LEDs, and relays.

You can connect the Extron IPA T RLY4 to the MLC to enable a relay function (to raise a projector screen, for example). To use the IPA T RLY4 with the MLC 104 IP Plus, do the following:

1.Use Global Configurator to set the MLC's digital I/O ports to output mode.

NRefer to the MLC 104 IP Plus User's Manual for the steps to set this port to output.

When the MLC's output signal is applied to one of the IPA T RLY4's relays, that relay’s NO (normally open) contacts close and its NC (normally closed) contacts open.

2.Connect the MLC's 12 VDC output to the IPA T RLY4's "C" (common voltage) terminal.

NRefer to the IPA T RLY4 User's Guide for information on how to wire the IPA T RLY4's relay outputs.

As shown in the illustration below, the digital I/O port is set to measure two states: on or off; high or low. Its input threshold voltages are as follows: low is <2.0 V and high is >2.8 V.
