The XIRO16 adds 8 relays and 8 digital inputs to your SPLat controller. It is easy to use, appearing simply as another 8 inputs and 8 outputs.
The output relays have ratings up to 5A. Six of the relays are wired for normally open contacts SPST/Form A (close on activation). Two are wired as change-over, SPDT/Form C. For electrical safety the relay contacts are separated from the control circuitry by 6mm board spacing, and the relays are UL and VDE listed/approved. See the documentation for more detail, including a link to the relay data.
The inputs provide provide industry standard NPN compatibility. Tying the input pin to ground (0V) registers as an On (True/logic 1) state. Leaving it open circuit or driving it to the positive supply voltage registers as an Off (False/logic 0). See the documentation for more detail.
