YOKOGAWA EXA PH202G-U-E PH ORP TRANSMITTER (XX2)

Description:

The Yokogawa DR1F-2 ER5 SUFF B is an input module designed to accept RTD (PT100) temperature signals, typically within a 0–200°C measurement range. It is part of Yokogawa’s data acquisition or recorder systems and functions as a signal conditioning card that converts resistance-based temperature inputs into usable signals for monitoring and control. These modules are commonly used in legacy Yokogawa recorder and DAQ systems and are often replaced during maintenance.

Applications:

The Yokogawa DR1F-2 module is used in process control and data acquisition systems for measuring temperature via PT100 sensors. The Yokogawa module is commonly installed in industrial recorders, monitoring systems, and control panels to capture temperature data in manufacturing, utilities, and process industries.
