Functional Features

• High-Precision Signal Acquisition: Equipped with 16-bit ADC (Analog-to-Digital Converter) to ensure accurate conversion of analog field signals, minimizing measurement errors for critical process parameters.
• Channel-to-Channel Isolation: Each of the 8 input channels features independent electrical isolation, preventing cross-interference between channels and enhancing system stability in noisy industrial environments.
• Wide Signal Compatibility: Supports multiple standard analog input types (current and voltage), eliminating the need for additional signal converters and reducing system complexity.
• Built-in Self-Diagnosis: Continuously monitors internal module status (e.g., ADC functionality, power supply, and communication links). Triggers alarms and sends diagnostic data to the DCS controller if faults are detected, enabling quick maintenance.
• Rack-Mounted Integration: Designed for seamless installation into ABB Advant OCS/Symphony Plus standard racks, with standardized backplane communication to ensure plug-and-play compatibility with the DCS.
• Environmental Robustness: Operates reliably within a wide temperature range and high humidity conditions, meeting the durability requirements of harsh industrial sites (e.g., chemical plants, power stations).
• Noise Immunity: Incorporates electromagnetic interference (EMI) filtering technology to suppress external electrical noise, ensuring stable signal transmission even in environments with heavy machinery or high-voltage equipment.
