1. General Information
- Model: AO3482
- Product Type: Safety-Certified Analog Output Module
- Manufacturer: TRICONEX (a business unit of Schneider Electric)
- Core Function: Receives digital control commands from TRICONEX SIS/DCS controllers, converts them into industrial-standard analog signals (e.g., 4–20 mA DC, 0–10 VDC), and transmits them to field actuators. Ensures real-time fault detection and fail-safe operation to maintain process safety. Complies with SIL 2/3 (Safety Integrity Level) requirements per IEC 61508, valid for use in safety-critical control loops.
2. Electrical Specifications
- Power Supply:
- Input Voltage: 24 VDC ±10% (supports redundant power input— a key feature of TRICONEX safety modules—to eliminate single-point power failures and minimize system downtime).
- Power Consumption: ≤10 W under rated load (excludes power drawn by connected field actuators, ensuring low energy consumption even in dense module configurations).
- Analog Output Specifications:
- Output Channels: 8/16 independent galvanically isolated channels (channel-to-channel isolation typically ≥500 VDC, preventing cross-signal interference and limiting fault propagation—critical for safety and signal accuracy).
- Supported Signal Types (Configurable per Channel):
- Current Output: 4–20 mA DC (sinking or sourcing, adaptable to different actuator wiring schemes).
- Voltage Output: 0–10 VDC / 1–5 VDC (optional, depending on firmware version and module variant).
-
- Output Accuracy:
- Current Output: ±0.1% of full scale (at 25°C; accuracy drift ≤0.01%/°C within operating temperature range, ensuring long-term signal stability).
- Voltage Output: ±0.2% of full scale (at 25°C; suitable for applications requiring moderate voltage precision).
- Resolution: 16-bit (enables fine-grained control of actuators, e.g., precise positioning of control valves).
- Load Capacity:
- Current Output: Maximum load resistance ≤500 Ω (compatible with most industrial actuators and signal transmission distances up to 1000 meters for 4–20 mA signals).
- Voltage Output: Minimum load resistance ≥1 kΩ (prevents voltage drop and signal distortion in long-distance wiring).
- Response Time: ≤100 ms per channel (time to transition from 0% to 100% of full scale, meeting real-time control requirements for fast-acting actuators).
- Protection Features: Built-in over-current protection (auto-recovery or latch-off mode, configurable via software) and short-circuit protection to prevent module damage from faulty actuators or wiring errors.
