Yokogawa Electric Corporation DX104-3-2 Chart Recorder

The Yokogawa DX104-3-2 F1/M1/R1/S120 DAQSTATION is a 4-channel paperless chart recorder designed for real-time monitoring, recording, and analysis of process signals in industrial data acquisition systems. It is commonly installed in control panels, power plants, chemical processing facilities, and manufacturing lines for continuous measurement of temperature, voltage, and other process variables. The unit accepts 4 input channels with voltage, thermocouple, RTD, and digital inputs, and presents data on a color LCD with real-time trend and waveform display. Data are stored in internal memory with removable storage options (CF or ZIP depending on configuration), enabling long-term trend review and event logging. Communication options include Ethernet via the DX100 interface, plus serial and optional fieldbus support for plant-network integration. Power is supplied from 100–240 VAC at 50/60 Hz, and the instrument is designed for panel-mounted industrial enclosures. Core functions encompass multi-channel monitoring, alarms, historical data review, and synchronized data logging across channels, making it suitable for monitoring temperature, pressure, flow, and electrical signals in demanding environments. Applications span power generation, oil and gas, water treatment, and general manufacturing operations where continuous data logging and trend analysis are critical. Common replacements include Yokogawa DX106 DAQstation Recorder and Yokogawa DX1006 DAQstation Recorder; GX10 SmartDAC+ Recorder is another nearby option.
