WebNov 17, 2014 · A simple 5V magnetic relay+diode+transistor would work for nearly any situation (and no calculations necessary), but they are too loud. I see two alternatives: Optocouplers and solid state relays. Unfortunately, most of them seem to have a maximum output of around 50mA ( I generally need 500mA or more ). WebBDT 78 Save BDT 21. It is a 1 Channel 5V Relay Board Module. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A. It has a trigger current of 5mA, and module working voltage of DC 5V. Each channel of the module can be triggered by a jumper to set a high level or a low level. Fault-tolerant design, even if the control line is ...
