Yokogawa AAI5‑S + ATK4A (Analog Output Module with Cable Adapter)
Product Introduction: A combined solution consisting of the AAI5‑S analog output module and the ATK4A 16‑channel cable adapter, designed for reliable signal transmission from the DCS to field actuators over long distances.
Technical Specifications:
- AAI5‑S: 16‑channel isolated analog output, 4–20 mA DC
- ATK4A: 16‑channel cable adapter, KS connector type
Detailed content
- Transmission Distance: Up to 1200 meters
- Isolation Voltage: 1500 V AC (module‑to‑system)
- Accuracy: ±0.1% of span
- Operating Temperature: -20°C to 60°C
- Power Supply: 24 V DC
Functional Features:
- High‑density 16‑channel output for space optimization
- Full isolation to prevent ground loops and cross‑talk
- ATK4A adapter enables long‑distance, noise‑immune signal transmission
- Easy wiring and maintenance with dedicated cable connectors
- Open‑circuit detection for fault monitoring
Application Scenarios:
Controlling control valves, positioners, and I/P converters in large‑scale process plants where long cable runs between the control room and field devices are required.
