Yokogawa SAI533-H03-S1
Product Introduction: An 8-channel analog output module designed for Yokogawa CENTUM VP DCS systems, supporting 4–20 mA signals with HART communication and full galvanic isolation. It is optimized for harsh industrial environments with ISA G3 corrosion resistance and wide temperature operation.
Technical Specifications:
- Output Channels: 8 isolated channels (module-level isolation)
- Output Signal: 4–20 mA DC (1.0–21.5 mA adjustable range)
Detailed content
- Accuracy: ±48 μA (at 25°C)
- Load Resistance: 0–750 Ω (at 20 mA)
- HART Protocol: HART 5/6/7 compatible, multi-drop support (up to 5 devices per channel)
- Isolation Voltage: 1500 V AC (1 minute) between outputs and system
- Data Update Cycle: 20 ms
- Power Supply: 24 V DC (system-powered)
- Operating Temperature: -20°C to 70°C (ISA G3)
- Terminal Type: Screw terminals (compatible with STA4S-00/10 accessories)
- Certifications: CE, CSA, ATEX (optional)
Functional Features:
- HART communication enables remote configuration, calibration, and diagnostics of field devices
- Module-level galvanic isolation eliminates ground loops and electrical interference
- High accuracy and low temperature drift ensure stable signal output over time
- Support for redundant DCS configurations to maximize system uptime
- Built-in open-circuit detection and fault reporting for predictive maintenance
- Compact design maximizes cabinet space utilization in control rooms
Application Scenarios: Oil & gas pipelines, chemical processing plants, power stations, and water treatment facilities where HART-enabled analog output signals control control valves, actuators, and flow controllers.
