8-Relay/7-Input INSTEON/X10 I/O Controller


EZIO8SA – Model # 3011A

For concurrent zigbee and Insteon operation see our IoT8-Z

You can trigger small devices, alarms, and events using incoming signals from sensors by setting up a centralized EZIO8SA.  It allows up to 7 incoming signals, which can trigger both the 8 wired outputs and a host of linked INSTEON devices through a PLM.  You can eliminate complicated wiring problems and create a responsive home control system.  Please note that this requires its own dedicated PLM to function.

Smart Possibilities:

  • Trigger lamps and overhead lights in response to detected motion
  • Use INSTEON keypads or switches to control multiple non-INSTEON devices
  • Sound an alert or chime when your garage door is opened


  • Requires its own dedicated INSTEON PLM like our EZIComm to function and 12V power supply (Please purchase the EZIO8SA Combo with PLM, if you don’t already have a PLM and power supply for the EZIO8SA.
  • Four opto-isolated digital inputs (3-30VDC)
  • Two inputs configurable as digital (0-1VDC for ON, 2-3VDC for OFF) or analog (10 bit resolution, 0-1023 points)
  • Dallas Semiconductor 1-Wire bus with support for 1 DS18B20 temperature sensor
  • Eight general purpose, Form-C relays (rated at 3A, 120VAC/24VDC)
  • Device can act as an INSTEON sender with each of the inputs able to trigger a unique group on/off command
  • Responds to INSTEON (direct or group) and X10 commands to turn on or off each of the 8 outputs
  • Extensive command set for maximum programming flexibility
  • Acts as a repeater of INSTEON signals
  • iSmartenit accessible
  • 1 year Smartenit warranty


EZIO8SA is a centralized input and output controller, managing incoming signals from up to 7 motion sensors, window/ door sensors and more while providing wired control over 8 small devices  itself in addition to its ability to send out INSTEON commands through the PLM.  This puts your input/ output control at the point of need, eliminating wiring nightmares.  You can now use simple sensors like magnetic door contacts to trigger multiple home automation devices at once or use your wireless keypads and remotes to control small electrical loads.

Triggering any of EZIO8SA’s inputs sends out an INSTEON group command, capable of controlling a number of home elements at the same time.  These inputs clan be wired to things like magnetic contacts, motion sensors etc. and can also be linked to INSTEON controllers.  So you can broadcast the same INSTEON group command via a contact closure or INSTEON command.  EZIO8SA’s outputs can be wired to small 3A at 120VAC devices and loads.  These outputs may be linked to INSTEON  or X10 commands, allowing you to control non-INSTEON devices via INSTEON or X10 commands.  So EZIO8SA is extremely versatile, allowing you a number of choices for triggering and controlling various devices.

EZIO8SA requires an INSTEON PLM, like our EZIComm to function as well as a 12V DC power supply.  You may purchase an EZIO8SA/ PLM combo from our store.

Outputs EZIO2X4 IoT8-Z IoT4R
Supported Protocols Insteon & X10 ZigBee & Insteon Insteon, X10 and WiFi
Controls Each output can be linked to an Insteon group to be controlled by an Insteon scene controller (Ex. Keypadlinc, Switchlinc, etc.)
INSTEON ‘All-Link’ A snapshot of the outputs can be recalled with a single group command (i.e. respond to a switch or a button on a Keypadlinc, ControlLinc, etc.)
Timers Timers from 1 second to 255 minutes can be set up to turn off each output

Ratings 30VDC/120VAC, 0.5A 24VDC/120VAC, 3A 30VDC/120VAC, 0.5A
Output Uses General purpose contact closures of small loads limited by relay voltage and current rating. General purpose contact closure of larger loads limited by relay voltage and current rating. General purpose contact closures of small loads limited by relay voltage and current rating.
Inputs EZIO2X4 IoT8-Z IoT4R
Controls For the digital (opto isolated) inputs, each input is ON when when current flows through the input or OFF when current is absent. Changes from OFF to ON and from ON to OFF can be used to control other ZigBee or Insteon devices. For analog inputs, voltage levels translate to points and On/Off transitions can be regulated by programmable trip points thresholds.
Timers Delayed OFF commands (from 1 to 255 minutes) programmable on each input. This timer resets (starts over) if a new ON command is received.
# of Inputs 4 6 None
Inputs Type 2 Opto-isolated (3-30VDC), 2 digital or analog (0-5VDC) 4 Opto-isolated (3-30VDC), 2 digital or analog (0-3VDC) N/A
