Digital Output Daugterboards
High Current Digital Ouputs
Some devices draw a bit more current than a logic device can deliver
can draw from a few milliamps to several Amperes of current. Driving those kinds of devices can be a hassle... Here is where the High Current Ouput Daughterboards come into play.
If your device draws less than 1A at less than 100V DC, you should be able to control it directly via the outputs of the high current daughterboards.
To power devices that need even more amps and/or require a higher voltage, as well as all AC based equipment, for example mains powered devices at 110V AC, 230V AC,... t hen you need to use a relay (which can be driven by the high current output daughterboards).
