Introducing the EXO Modbus Signal Output Adapter from YSI, designed with and engineered for compatibility with the EXO sonde platform. As technology continues to develop at record pace, it's more critical than ever to have a flexible sonde that can keep up.

A fundamental part of the EXO Sonde platform is the ability to adapt its communication output to match different monitoring applications. Simply configure a sonde with this adapter and the instrument is then compatible with industrial SCADA systems, or PCs and tablets with USB connectivity. Converts the proprietary signal from an EXO Sonde into a Modbus protocol over RS-232 or RS-485.
