I am looking at buying a bunch of solid state relays to MIDI'fy an old keyboard / synth.
I was planning to use it across the key contacts of it's keyboard.
Anyway, I've sourced a bunch of "LH1547" solid state relays, but an a bit confused.
On the schematics, there is a diode across the S - S' junction.. but the blurb says that the "LH1547 is a SPST normally open unidirectional relay that can switch DC signals"...
Does this statement seem to contradict itself? Unidirectional & DC ? The diode ?
Can someone please clarify this for my poor self?
Kind regards
Mike
