Functional Features
1. High-Fidelity Signal Acquisition
- Configurable Channels: Each of 8 inputs independently supports voltage/current signals (4–20mA, 0–10V, ±10V) without external conditioners .
- Galvanic Isolation: Prevents noise interference between channels and backplane, critical in high-EMI environments like substations .
2. Integrated Diagnostics
- Real-time detection of open circuits, sensor failures, and signal over-range, reducing unplanned downtime .
3. Seamless System Integration
- Plug-and-Play Compatibility: Direct integration with AC 800M controllers and S800 I/O bases .
- Multi-Protocol Support: Native PROFIBUS/PROFINET connectivity vs. third-party gateways for Modbus .
4. Robust Industrial Design
- IP52 Front / IP50 Rear Protection: Resists dust/liquid ingress in control cabinets .
- Vibration Tolerance: Certified for 5g RMS (10–500 Hz) in heavy machinery .
