Model 8020-59 · 8020-59 PLC

The Model 8020-59 Vibrating Wire (VW) to Analog Converter provides a simple way to connect GEOKON vibrating wire transducers to data acquisition systems, which are not capable of reading frequency signals nor able to generate the proper signals required to excite VW transducers. The converter can operate with single transducers, as a stand-alone device, or with multiple transducers in conjunction with the Model 8032 Multiplexer. The converter is powered using either a 12 V or 24 V supply.

The Model 8020-59 PLC provides the capability to control the 8020-59 VW to Analog Converter and/or the Model 8032 Multiplexer via relay closures (Ground Referenced) as provided by most Programmable Logic Controllers (PLC).
