Better still each channel has an indicator LEDs which means at a glance you can see what’s happening with your setup. Even the analog channels have dimming LEDs that allow you to see the value they are currently sensing – swish!
It’s compatible with all version of Raspberry Pi that have the 40-pin GPIO header (3, 2, B+, A+, Zero) and comes fully assembled:
3 x 24V @ 2A relay (NC and NO terminals)
3 x 12-bit ADC @ 0-24V
3 x 24V tolerant buffered inputs
3 x 24V tolerant sinking outputs
15 x channel indicator LEDs
1 x 12-bit ADC @ 0-3.3V
3.5mm screw terminals
Power, Comms, and Warn! LED indicators
Extra GPIO: TX (#14), RX (#15), #25
As ever, we’ve made a super-simple to use Python library to take advantage of Automation HAT’s multitudinous functions, with examples to get you started.
Our input, output and relay examples show you how to read the analog and digital inputs, switch the outputs on and off, and control the relays.
Loads for the buffered outputs should be switched on the ground side, i.e. 12/24V (from supply) -> load -> output terminal -> ground (from supply)
The relays can tolerate up to 2A each and should be switched on the high side
The sinking outputs can sink a maximum 500mA total across the 3 outputs, so if you use a single channel you can sink the whole 500mA across it.
The accuracy of the ADC is ±2%.
Do not use to switch mains voltages!
