Insteon Remote Control Plug-in Low Voltage Controller

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).

    Works, but only for a few years. Review by TechGuy
    Works, but only for a few years.

    Using IO-Linc to automate a ToggleLinc based on input from a magnetic reed switch mounted to projector screen. It turns the light off when screen drops, and back on when screen is retracted all the way. The ToggleLinc continues working well, but I wish the IO-Linc would be as reliable. Every couple years I am having to replace the IO-Linc.

    Working as expected Review by Steve
    Working as expected

    i used the N.O. contact on the low voltage controller to turn my spa heater on/off remotely using a four scene mini remote. Works great so far. I use insteon to control the spa pump and the spa jets as well. So far so good!

    Another Update Review by OldSurferDude
    Another Update

    The intermittent communication came back. What really fixed the problem was a 2992-222 Range extender (another $40). I have 30 some power line only and Dual-band devices. It surprises me that I don't have at least one Dual-Band on each phase.

    I tried the 2443 access point and it didn't work in my application, bridging from an existing Dual-band device.

    Updated review Review by OldSurferDude
    Updated review

    In my previous review (which never showed up here), I gave it one star because it started operating intermittently. I would receive a command but not send the status of the sensor or respond to queries. (heat related?)

    In that state, it was useless to me. Before buying a new one, which I loathed to do, I decided to take it apart. I hoped to find one of two fixable problems: a blown capacitor or contamination.

    I suspected the former because in other forums, this was the fix. The latter because it seemed to be a transmission problem and not a reception problem.

    It was the latter, easily fixed by scraping the orange/clear splotch on the PCB. I also suspected poor solder joints and carefully looked at all of them (in another life I was an electronics manufacturing engineer) as this could cause signal problems. I was delightfully surprised that the manufacturing was quite good. (thus the three stars).

    I didn't give it more stars because, to me, it is obvious that the management does not spend enough on R&D. Smarthome was clearly the leader in the field of home automation but totally dropped the ball with underfunded projects like The Hub. Universal Devices' ISY994 is what The Hub should have been. Smarthome is doomed if does not fully fund the many obvious project that it could do. For example, this I/O device could easily be 8 bits wide at very little additional cost. Reliability is not adequately tested, either.

    Intermittent when the temperature gets warm Review by OldSurferDude
    Intermittent when the temperature gets warm

    It's been pretty pretty warm here in Southern California for the past month. My garage door faces west and it gets quite warm in the garage when the door is closed ... where the sensor is. At some point, the device only worked intermittently. That is, would receive commands to change the state of the relay, but would not send the status of the sensor. Eventually I reset it to factory defaults and reprogrammed it. I will be looking for a replacement.

    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

    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.

    2 Bad ones in 2 years

    Title says it all. First one was over 2 years, second one is in warranty. Will try to return.
