The Z-tronics pipe organ relay was developed 20 years ago in the early days of experimentation with multiplex relay switching systems. At that time, poorly designed systems had given multiplexing a bad reputation. Bill Zabel, an electronics design engineer in Fort Wayne, IN, developed a simple system specifically for pipe organ applications. His design proved to overcome the shortcomings of previous systems and was awarded US Patent 4,092,895.
The Z-tronics system is made up of simple modules, each completely assembled and tested, connected by hard wiring to incorporate the features and unification of a particular specification. Because the system was patented, complete documentation, schematic drawings, and theory of operation is included. Anyone with the ability to use a soldering iron can configure the building blocks into an organ relay.
By supplying full details of the system, thus enabling the builder to assemble it, the builder is able to trouble-shoot and make simple repairs. No longer is the solid-state system a mystical "black box" which has to be returned to the manufacturer for repairs.
The Z-tronics system logic blocks are simple to understand. All signals are at audio frequencies which can be traced with a simple piece of diagnostic equipment, a crystal earphone.
