This circuit is limited to 5volts as a family plc input output so is not really suitable for most Tachometers as it is close to or on the threshold. A pull-up resistor for those that are following this paint drying exercise would give it the extra it needs
Hi minijcar,
Your text "this paint drying exercise" made my day and summed up how I feel about what I thought was going to be a 1 hour job to install a new tacho on a Sunday afternoon
, yet it has turned into a research project on a topic I know little about.
Thanks for your help, will hopefully try out the diode this week end and see what happens.
Accuspark got back to me and recommended I contact
