Humidity: 5–95% (non-condensing)

Protection: IP20 (die-cast aluminum housing)

Main Features

Dual-Baud Communication: 4800 baud (system) / 600 baud (field) for high-speed digital data and analog backup to ESD.

8-Channel Isolation: Fully isolated channels eliminate crosstalk and contain faults.

Smart Device Support: Native interface for Foxboro intelligent transmitters (digital values, diagnostics, status).

2-Wire Operation: Single twisted pair carries power and data, reducing wiring cost.

Hot-Swappable: Online replacement without system shutdown.

Redundancy: Supports 1:1 redundant fieldbus communication.

Applications

Process industries: Chemical, power, oil & gas, water treatment.

Smart transmitter interface: Foxboro intelligent field devices (temperature, pressure, flow).

Digital process data + analog ESD backup in hazardous areas.

Harsh environments: High dust, EMI, corrosive (Class G3).
