Innovation Point 1: Advanced Signal Isolation The AD908AC utilizes galvanic isolation with 2500 VDC resistance, effectively blocking ground loops and electromagnetic interference (EMI). In power plants with high-voltage equipment, this feature reduces signal degradation by up to 80% compared to non-isolated modules, ensuring data integrity for critical control decisions.
Innovation Point 2: High-Accuracy Data Conversion Its 16-bit sigma-delta analog-to-digital conversion technology delivers ±0.05% full-scale accuracy, enabling precise measurement of process variables. In pharmaceutical manufacturing, where strict batch control is essential, the module’s accuracy ensures consistent product quality by maintaining ingredient ratios within tight tolerances.
Innovation Point 3: Rugged Industrial Design Built with temperature-resistant materials, the AD908AC operates reliably in extreme conditions, from sub-zero warehouses to high-heat refineries. Its robust casing also resists vibration and moisture, extending lifespan by 30% in harsh environments like mining operations.
