Material Composition
Industrial-grade housing with high-quality serial interface ICs and isolation transformers.
Structural Characteristics
Standard FBM form factor with DB9 and terminal block serial connectors. Front panel displays communication activity LEDs.
Working Principle
Receives serial data from connected devices, converts it to fieldbus-compatible format, and transmits it to the controller while performing reverse conversion for outgoing commands.
Installation Requirements
Install on a compatible baseplate. Use shielded serial cables and ensure proper termination for RS-485 multi-drop configurations.
Usage Precautions
Verify baud rate, parity, and stop bit settings match connected devices. Ensure proper grounding of serial shields to prevent noise interference.
