We have a project where we are creating a printed circuit board that will interact with a commercial washing machine's mechanical timer. The circuitry has to be able to read when 115VAC is present or in the case of a 230VAC machine when 230VAC is present. Is there more than one approach when it comes to picking off that part of the logic within the circuit board. Since I am the person underwriting the project ... I am hoping the relatively young electronic engineer is not in over his head when it comes to the most reliable & durable way of reading the presence of the proper voltage. We are hoping to use the same components on that part of the board for sensing either 115VAC or 230VAC so we do not have more than one prototype for the board itself.
