I/O Linc - Insteon Low Voltage / Contact Closure Interface ( 1 In / 1 Out )

Insteon Remote Control Plug-in Low Voltage Controller

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
* The included Insteon IO Linc 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 IO Linc module with Insteon RF-only or Dual-band devices.

  • What's Included
  • 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).

    Love the function, but it's not perfect Review by Viper
    Love the function, but it's not perfect

    I just bought an IOLinc to replace an IOLinc that went bad. The one that went bad would report it's status, but wouldn't control the relay, then it started strobing (flashing on and off constantly) and no longer reported status. So, reliability...I'm not sure. I also noticed that the IOLinc is only good down to 32 degrees, but it is sold as a garage door solution (where I use mine). My garage is detached and gets down to -40 degrees. A definite mismatch between marketed solution and technical specifications.

    Garage door sensor. Review by Otis
    Garage door sensor.

    The relay works, but the one thing mos important to me does not. This is likely a software issue. When I open my Insteon app, the app does not show if the door is open or closed. If you open the door, while using the app, it displays correctly, but, if you check the app minutes later... no display of the sensor status shows... rendering the device/app all but useless as a garage door monitor. FIX THIS!

    Using for Portable Thermostat Support Review by Lou
    Using for Portable Thermostat Support

    Paired this with a 2441ZTH Portable Insteon Thermostat to control my first floor zone. Wiring was easy enough, but it is a bit tricky to get the state of the Normally Open/Normally Closed pins working as expected. Despite the naming of the pins, you can actually make them behave either way, though they will be complements of each other. Just read the user guide section on "Linking an INSTEON Controller to Control the I/O Linc Output Relay". Basically put the relay in the state you want it when an "ON" command is received (e.g. with the relay closed, using the N/O pins) before linking. Working flawlessly so far.

    Don't last Review by David
    Don't last

    I have purchased several units over the years. They only last 2 to 4 years before failing. Currently looking for a better I/O device.

    More Parts Review by jmight
    More Parts

    Needed more parts to get this up and running namely a range extender to convert from wired to wireless communication. once the Extender was installed it communicated perfectly with my Hub.

    Not compatible with Hub Pro Review by James
    Not compatible with Hub Pro

    Although it worked to complete the door strike setup, this device is NOT compatible with the Hub Pro. Would REALLY like to have this updated to work with that.

    Does what I need but falls short Review by Andrew
    Does what I need but falls short

    Bought two of these to control my home theatre curtain: one to open, one to close. It's unfortunate that I needed two for this purpose, and even more so that they frequently miss commands from the Insteon Hub, leaving the curtain open after an automated show or failing to open the curtain at the start of a movie. All my other Insteon components (several dimmers and on/off outlets) work well, so I think I'm experiencing some of the same problems here as others have.

    Thrilled it finally works... Review by Sorebikr
    Thrilled it finally works...

    Was actually very difficult and frustrating to install. My set-up: Insteon low-voltage interface, new hub and 3/4" shutoff valve. After installing...nothing. Was is the wiring? The android software on my phone? Very tough to trouble shoot. Turns out my I/O wasn't plugged into an outlet that was on the same phase as the hub. Same phase? That was news to me. Turns out the I/O communicates with the hub over your house' wiring, not over wifi. Which means only certain outlets will work in the house.

    Eventually, after an hour on the phone with support we were able to get it working, and I LOVE it. But still...
