Expand your control
Put simply, the I/O Extender adds a whole swathe of extra physical connections to your S-PLAY SP1-1 system, enabling you to create many more triggers and events than were previously possible to be controlled by the same unit.
With 20 general-purpose input/output (GPIO) digital inputs, you can add multiple sensors, wall switches and much more.
The 4 relay inputs are ideal for operating mechanical devices such as curtains, pumps, winches or lifts.
You also get two analog inputs for light sensors, pressure sensors, temperature sensors, joysticks … pretty much any analog signal device you like.
Flexible networking
The I/O Extender is equipped with two Ethernet ports to create a dedicated, standalone S-PLAY show playback network. Easy to configure and monitor via the S-PLAY's web interface.
Always in sync
The I/O Extender is engineered to ensure real-time data exchange and synchronized control with your S-PLAY device. It's also effortless to configure, with most settings easily managed via the S-PLAY's own web interface.
Versatile power input
Flexible power options with a 12-24V DC screw terminal input.
Seamless integration
Ideal for projects requiring additional signal management and control capabilities. Add multiple I/O Extenders to your S-PLAY setup to build a larger, more powerful network. Choose from flexible installation options, including half rack, full rack, or surface mount, to perfectly fit your setup.
3-year warranty
ENTTEC are proud to back up the confidence in our research, engineering and quality control with a 3-year return-to-base manufacturer warranty on this product.

Join Nic, as he takes a first look at the S-PLAY I/O Extender and delves into the additional functions that this nifty device will enable you to do.

Example of a larger network system using the I/O Extender

For a simpler playback setup, users can bypass the network switch by connecting the S-PLAY device and the other node directly to the I/O Extender’s inbuilt network switch. This creates a dedicated network, allowing preset shows playback without the need for a complex network infrastructure.
