Flex I/O Ports

Some Extron IP Link® products have one or more Flex I/O ports that can interface with a variety of devices such as sensors, switches, LEDs, and relays.

"Flex I/O Port" is defined below.

Flex I/O Ports – Can be configured in three different ways:

• Analog in

• Digital in

• Digital out

Flex I/O ports allow IP Link devices to accept an input voltage and then send out a serial command or trigger another event.  These ports can support TTL and analog signals from 0 to 24 volts, allowing a wide variety of devices to be controlled and monitored.

Flex I/O Ports can be configured to receive analog voltages for use with photo sensors, level feedback, strain gauges, thermocouples, variable potentiometers and other devices. Incoming analog voltages from 0 to 24 volts are sampled with 12-bit precision.

For example, a thermal sensor installed in an equipment rack can be connected to one of the Flex I/O inputs, and the IP Link device can be configured to send an e-mail message, turn on auxiliary cooling fans and turn off equipment if the rack temperature exceeds a specified temperature value.

Configured as digital inputs, the Flex I/O ports can connect to switches, motion sensors, moisture sensors and tally feedback.  This provides the ability to receive status from a variety of devices including projector lifts, motorized projection screens, room partition switches, and push buttons.

When configured as digital outputs, the Flex I/O ports can drive LEDs, 24 volt incandescent lamps, an additional external power supply, or other devices that accept a TTL input signal. For applications that require contact closure control, the Flex I/O ports can interface with an Extron IPA T RLY4, an IP Link accessory featuring four isolated relays.
