2. Functional Features

Redundant Design: Module pairs provide redundancy at the Fieldbus Module (FBM) layer, enhancing system reliability and ensuring uninterrupted data transmission even under harsh conditions.
HART Protocol Support: Compatible with the HART protocol, each input channel is equipped with a dedicated FSK modem, enabling bidirectional digital communication with HART field devices. This allows access to additional device information such as status and fault data.
Electrical Isolation: Each of the eight input channels is electrically isolated from each other, from ground, and from module logic, improving anti-interference capability.
High Precision: Each channel achieves high precision via Σ-Δ conversion, converting 4-20mA input signals from HART devices into digital data. It supports HART universal commands required for interfacing field devices with the Foxboro DCS database.
Overload & Short-Circuit Protection: Integrates overload protection (automatically cuts off output when current exceeds limits) and short-circuit protection (shuts down output during short circuits), enhancing system safety.
