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.
1.
Use Global Configurator to set the MLC's digital I/O ports
to output mode.
N
Refer 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.
3.
Connect the MLC 104 IP Plus' digital I/O wires (from
digital I/O ports 1, 2, and 3) to the IPA T RLY4's inputs
(1, 2, and 3), as shown below. The Extron Comm-Link
(CTL and CTLP) cable is recommended for these
connections.

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.
