I currently have a piece of equipment that uses 2 NPN proximity sensors. Both sensors monitor the same toothed pulley on a machine are used as inputs to independant counting circuits.
I would like to modify the set up, so that only 1 sensor is used. The resulting system will look something like the diagram below. Is there anything commercially available (perhaps from RS Components) that I can use to provide the 2 isolated outputs for loads A & B, from a single input fom an NPN sensor ?
TIA, woodglass
