Yokogawa UR5AG3-500N-1S E-2SA-N
Working Principle: The UR5AG3 uses an electromechanical pen-drive system. Input signals (voltage, current, thermocouple, RTD) are converted by internal circuitry and drive a servo motor with pen arm across a moving chart paper. The pen deflects proportionally to the input signal, creating a continuous analog trace. The chart paper advances at selectable speeds (25mm/h to 600mm/h). Alarm contacts close when input exceeds preset thresholds.

Applicable Industries:
- Water & Wastewater Treatment
- HVAC & Building Automation
- Food & Beverage Processing
- Pharmaceutical Manufacturing
- Chemical Plants (Non-hazardous areas)
- Power Generation (Auxiliary Systems)
Advantages & Highlights:
- Pure analog recording — no data loss during power failure
- 3-channel simultaneous recording on 500 mm wide chart
- Built-in alarm contacts — no external relay required
- Wide input compatibility (Type E) — accepts TC, RTD, mA, V, and contact inputs
- Mechanical reliability — proven technology with decades of field service
- Legal record — paper chart serves as tamper-proof documentation
Installation Requirements:
- Mount on flat vertical surface using M4 screws (2 points) or DIN rail (if adapter available)
- Ensure adequate ventilation — minimum 50 mm clearance on top and sides
- Connect field signals to rear terminal block — observe correct polarity
- Set chart paper speed and pen zero before operation
- Configure alarm setpoints using front panel knobs
Usage Precautions:
- Replace ink pen cartridges regularly (typically every 6–12 months depending on usage)
- Use only Yokogawa Type 2SA chart paper — other sizes will not feed correctly
- Do not operate in environments exceeding +50°C or below 0°C
- Clean pen tip with approved solvent if recording becomes faint
- Backup critical data digitally — paper charts degrade over time
