Functional Features:
- Plug-in removable storage — data can be transferred to PC via card reader
- Supports continuous data logging to SD card as backup to internal memory
- CSV format — directly importable into Microsoft Excel, Yokogawa DAQSTANDARD, or custom SCADA
- Hot-swappable — can insert/remove card during recorder operation (data integrity protected)
- Password protection available on compatible recorder models
Material Composition:
- Module Housing: ABS engineering plastic (UL94 V-0)
- SD Card Slot Contacts: Gold-plated phosphor bronze
- SD Card: Standard commercial SD/SDHC card (user-supplied or Yokogawa recommended)
Structural Features:
- Front-panel mounted slot on UTAdvanced recorder
- Push-push ejection mechanism — card clicks in/out
- LED indicator on recorder shows SD card status (recording, error, full)
Working Principle:
The recorder writes process data (trend, alarm, event logs) to the SD card in CSV format at user-configurable sampling intervals. Data is written in sequential blocks with file header containing timestamps, channel names, and units. The SD card operates as a standard mass storage device — no proprietary format, ensuring universal compatibility.
Advantages & Highlights:
- Portable data archival — remove card and store off-site for compliance
- No network required for data backup — useful in isolated installations
- Low cost per GB compared to proprietary memory solutions
- Simple data transfer — card reader connects to any PC via USB
Applicable Industries:
- Oil & Gas (upstream/downstream)
- Chemical Processing
- Power Generation & Distribution
- Water Treatment
- Manufacturing (batch recording for FDA/GMP compliance)
- HVAC & Building Automation
Installation Requirements:
- Insert SD card into the front panel slot on the UTAdvanced recorder
- Ensure card is formatted as FAT16/FAT32 (recorder auto-formats on first use)
- Use Class 4 or higher speed SD card for continuous high-speed logging
- Do not remove card during write operation (wait for recorder to indicate “safe to remove”)
Usage Precautions:
- Use industrial-grade SD cards for long-term reliability in high-temperature environments
- Do not use SDXC cards — only SD/SDHC up to 32 GB are supported
- Format card using the recorder — do not pre-format on PC (may cause compatibility issues)
- Back up data regularly — SD cards are not designed for infinite write cycles
- Store cards in anti-static sleeve when not in use
