The exposed rear contacts of the PCB may present a bit of a safety issue if touched, but I don’t anticipate use with anything more than about 24V. Instead of Ersin 362, this particular board was assembled using Multicore 0.8mm 60/40 Hydro-X flux solder which seems to be a more effective flux but requires water-based cleaning and has a bit of an irritating smell. Tests of this board were successful – the relays clicked in and…
