• Redundancy: Not supported (single‑module operation only).

Core Functions

1. 2‑Channel High‑Speed Serial Bridging: Connects DCS controllers to third‑party serial devices with baud rates up to 115.2 kbps for low‑latency data exchange.

2. Multi‑Protocol Support: Handles ASCII, Modbus RTU/ASCII, and custom protocols for flexible integration with diverse field devices.

3. Enhanced Electrical Isolation: 250 Vrms channel‑to‑channel isolation suppresses noise and ground loops in harsh industrial environments.

4. Real‑Time Diagnostics: Detects and reports communication errors (framing, parity, timeout) and channel faults for rapid troubleshooting.

5. Conformal Coating: Protected against dust, moisture, and chemical vapors for reliable operation in extreme conditions.

6. UCN High‑Speed Communication: Transfers serial data to the DCS controller via 1 Mbps UCN backplane for real‑time process monitoring.

Application Scenarios

• Process Industries: Chemical, petrochemical, oil & gas, power generation, pulp & paper, pharmaceuticals, water treatment.

• Third‑Party Device Integration: Connects DCS to PLCs, flow meters, gas analyzers, temperature controllers, and serial printers.

• Legacy System Upgrades: Interfaces older serial devices with modern Honeywell TDC3000/TPS/Experion PKS DCS.

• High‑Speed Data Logging & Printing: Enables DCS to send high‑volume process data to serial printers or loggers for record‑keeping.
