Factory Refurbished Insteon I/O Linc Contact Closure Interface

Expand your Insteon Network to monitor and control low voltage and contact closure devices
  • Monitor and control pool valves, electric door strikes, garage doors and more using your Insteon network
  • 4 output relay modes allow you to control many different types of devices
  • Control Insteon lights and appliances using standard sensors
  • Contains 1 sensor input and 1 output relay (NO/NC)
  • For control from an Insteon Mini Remote, you will need a Range Extender or other dual-band Insteon devices*
  • Can be used with an Insteon Hub however the included IOLinc module communicates via powerline only, so you may need a Range Extender or other dual-band Insteon devices*
  • Award-winning Insteon technology provides superior performance and reliability
  • This product is refurbished and sold as-is - see note below for details
  • This item is a retail packaged version of the I/O Linc (2450). Apart from packaging it is functionally identical.
* The included Insteon IOLinc module communicates over powerline only, which may cause issues if you are trying to remotely operate Insteon devices on a different electrical phase (circuit) or from a Mini Remote. We recommended adding a Range Extender on the same phase to bridge the IOLinc module with Insteon RF-only or Dual-band devices.

  • This refurbished product is tested to work like new, with limited to no signs of wear. The refurbishing process includes inspection, functionality testing, and repackaging. May not have original packaging. Limited 30 Day Warranty – all sales are final. Only exchanges will be accepted for products found to be defective.

    The latest Insteon plug-in module, I/O Linc, lets you monitor and control any low voltage devices such as alarm sensors, electric door strikes, and contact closures as part of your Insteon home automation network. With one dry-contact sensor input you can control many Insteon devices throughout the house. Plus, use the built-in single-pole double-throw (SPDT) switch, connect any low voltage-powered device for continuous or momentary operation. Create your own remote-control door lock using an electric door strike and power supply or use a security sensor turn Insteon controlled lights on or off.

    Required Accessories
    Sensor wire: 16 - 28 gauge wire fits, but 20 - 22 gauge recommended

    I/O Linc's flexible output relay can control many different types of low voltage devices, from pool valves to electric door strikes to garage doors due to its different relay modes. When controlling devices like pool valves, you will want the ability to leave it on for an extended period of time, giving it plenty of time to fill the pool. As it approaches the desired water level, then you can remotely turn it off. For devices like electric door strikes, set I/O Linc's output relay to momentary, allowing you open the front gate using a RemoteLinc or any other Insteon controller. A third version of I/O Linc's momentary mode allows you to remotely press your garage door button with an Insteon On command, but only if your garage is currently closed. This allows you to open your garage with On command and close it with an Off command. Because I/O Linc uses a garage door sensor to know whether the door is open or closed, it only controls the garage when it needs to.

    Controlling Two Separate Loads
    With the addition of a DPDT Relay Board, the I/O Linc is capable of switching two separate loads on and off together. In this configuration, the I/O Linc could control two different loads of varying voltages (i.e. one high voltage and one low voltage load) or two higher current loads (up to 7A @30VDC each).

    Works like new Review by kdjerred
    Works like new

    It came in an original box. Looks like new and appears to work with no problems. I have purchased 3 over the past few weeks. I am using them as controllers for refrigerator and freezer failure sensors. I recommend them as a cost saving way to expand your Insteon network. In the past couple of years I have used the I/O link for two fire place controllers when paired with Insteon portable thermostats and as garage door controllers. I have never had a problem with any of them.
