Functional Features:

• Dual-channel simultaneous recording with independent scaling
• 2 alarm relay outputs with user-configurable setpoints (A4)
• Ethernet communication (M1) for data upload to host systems
• Redundant power supply (R1) for critical applications requiring uninterrupted operation
• USB port for data export via CSV format
• Event recording with timestamp accuracy of ±1 second
• Trend display with up to 8 pens simultaneously

Structural Characteristics:

• Front panel mountable (panel cutout: 138 mm × 138 mm)
• Die-cast aluminum housing with epoxy-coated finish
• Gasket-sealed front bezel for IP66/NEMA 4X protection
• Wall-mount or panel-mount installation

Working Principle:
Analog input signals are converted by a 16-bit A/D converter and processed by the internal microprocessor. Data is stored in NAND flash memory and displayed on the color TFT LCD. Alarm conditions trigger relay outputs based on user-defined thresholds. Communication via Ethernet allows remote monitoring through Yokogawa PRM software or third-party SCADA systems.

Advantages:

• Zero paper consumption — fully digital recording
• Long-term data storage with no degradation
• Redundant power option ensures continuous operation
• Wide input compatibility eliminates need for signal conditioners
• Compact design saves panel space compared to chart recorders

Applicable Industries:

• Oil and Gas
• Chemical and Petrochemical
• Water and Wastewater Treatment
• Food and Beverage
• Power Plants

Installation Requirements:

• Panel cutout: 138 mm × 138 mm, depth minimum 120 mm
• Mount vertically with the display facing the operator
• Provide dedicated 100–240 V AC power circuit for R1 redundant configuration
• Use shielded cables for analog input signals
• Ground the chassis to the plant grounding system

Precautions:

• Do not apply input signals exceeding the rated maximum (e.g., 30V DC or 30mA)
• Ensure the recorder is powered off before connecting or disconnecting field wiring
• Perform periodic backup of recorded data via USB or Ethernet
• Do not install in direct sunlight or environments exceeding +50°C
