Before and after photos of TECC C20CPU73 RetroFit of obsolete Omron Sysmac C20 CPU73 on a Cemco Residence lift built by ESI for Cemco. Built late 80s to early 90s. Exact operation as original in the C20 but in a brand new and currently in production Omron PLC and it installs wire for wire. Nothing else needs to be touched. This can be done for any elevator using the Omron PLC system. Contact TECC for more info/pricing/availability.
