General Model DO402G Specifications Dissolved Oxygen Converter GS 12J05D02-00E [Style: S3] Flexibility, reliability and low maintenance are among the benefits provided by the EXA DO402G dissolved oxygen converter. Designed to meet the exacting re- quirements of measuring dissolved oxygen in the mod- ern industrial environment, it contains many features to ensure the best precision whatever the application. This 4-wire converter is housed in a robust IP65, NEMA 4X, CSA Type 3S field mountable case. Two mA outputs, four relays, digital communication and a clear LCD make the DO402G a truly comprehensive package. The DO402G features PI control on both the auxiliary mA output and the pulse proportional relay outputs, DO402G　 Dissolved Oxygen Converter thus avoiding the need for a separate controller. The famous EXA sensor diagnostics are now expanded with a logbook facility in combination with the RS485 two wire communication software option. This can be used to record events like calibration and diagnostic messages, and to update configuration of the converter remotely. The DO402G accepts inputs from optical, galvanic and polarographic sensors. Percent saturation, mg oxygen/l water, and ppm DO can be displayed and transmitted. DO70G　Optical Dissolved Oxygen Sensor Compensation for atmospheric pressure altitude, salin- ity and temperature are included for the best accuracy of measurement. Features • Versatile sensor inputs • On-line sensor checking monitors integrity of mem- brane • RS485 communications interface • Event logbook in software • Four fully configurable SPDT contact outputs • Two fully configurable mA outputs DO30G　Galvanic D
