HF2018
- Product Code: HF2018
Overview
The RS485 concentrator is an industrial-grade bus expansion device that uses optoelectronic isolation technology to achieve electrical isolation between master and slave devices, effectively suppressing signal interference caused by ground potential differences, static electricity, lightning strikes, and ground loops. The product can expand 1 RS485 master interface into multiple outputs, with up to 128 devices connectable on a single bus and a maximum communication distance of 1200 meters. Featuring wide voltage power supply, adaptive baud rate, and maintenance-free design, it can be quickly deployed and operate stably in various scenarios such as industrial automation, data acquisition, and remote communication.
