Adaptive HART Communication Integration

The T8480 supports HART 7 protocols, enabling bidirectional communication with smart field devices for remote calibration, diagnostics, and configuration. This feature enhances predictive maintenance in applications like refinery valve control, where real-time parameter adjustments are critical. Field supply voltages (18–32 VDC) ensure compatibility with legacy actuators while maintaining signal integrity.

Redundant Precision Calibration

Features a ±0.1% full-scale calibration accuracy at +25°C, degrading to ±0.25% across an operational range of 0–60°C. Unique to this module is its ±350 µA standby swap bump tolerance, which prevents output disruption during maintenance or redundant system transitions.

Dynamic Power Group Isolation

Five isolated power groups provide 50 V reinforced continuous isolation and 250 V basic fault isolation between channels, tested at 2,436 VDC for 60 seconds. This design mitigates cascading failures in high-voltage environments like offshore platforms, ensuring uninterrupted operation during transient surges.
