How do I convert from 110vac to 240vac?

To convert your HI 2110WI, HI 2151/30WC or HI 2160RC from 110vac to 240vac, or from 240vac to 120vac, please review the attached Tech Note. There are separate tech notes for the Wall Mount version (WS) and the Panel Mount version (WC). There is also a separate process with photos for the wall mount style.

Other Hardy Instruments have universal power supplies and will work with either 120vac or 240vac input. All PLC modules are powered by the PLC directly.
