Electronics Kit
Kit 01 - Relay Board
Our first electronics kit. It is a simple relay board which is designed to
allow a very small current (125uA at 5V) to switch higher voltages and currents
(max 2A at 50V). The relay used provides two independent changeover switches.
The kit was initially designed for model railway use to control memory wire motors
and turnout (point) polarity, but it can be used for any suitable purpose.
More details, and construction notes, may be found
here
on the kit's instruction
sheet (pdf 300K).
