Technical Specifications 24VDC power supply, isolated communication port. Operating temperature: -40℃ ~ +70℃, compatible with common industrial communication protocols.

Functional Features Real-time operating data upload, remote parameter modification, communication fault diagnosis, data verification and retransmission.

Application Scenarios Power plant centralized monitoring, generator remote control, multi-controller interconnection.

Performance Parameters Low transmission delay, stable long-distance bus communication, strong electromagnetic interference resistance.

Structural Characteristics Pluggable communication module, communication running and fault indicator lights, port shielding structure.

Working Principle The module reads operating data from the main controller, packs data into standard protocol frames and transmits to upper equipment. It also receives remote commands and forwards parameter instructions to the main control board.

Installation Requirements Use shielded twisted-pair communication cables, ground shielding layer at one point, separate from power cables.

Usage Notes Set station address, baud rate and parity correctly before commissioning, avoid hot plug during data transmission.
