I have a couple industrial valves that need to be changed out that currently have 120 volt readbacks to input to a PLC. The replacement valves that were ordered and received have 24 VDC readbacks. Does anyone know a means of converting the 120V at the valve to 24 VDC and then back to 120V after the readbacks? It would be preferrable to have the conversion means at the readbacks so we don't have to re-pull the wiring due to incorrect insulation color. The panel where the PLC is located does not have 24 VDC, and the PLC does not have 24VDC input cards. Trying to figure out a painless way to do this.
