Multi Protocol Industrial Communication Board SL241106 CAN Bus RS485

SL241106 (Ver: 250616) is a highly integrated industrial communication interface board engineered for seamless data exchange and protocol conversion in complex automation systems. It combines CAN bus, RS485, and Ethernet (RJ45) connectivity onto a single compact platform, enabling versatile networking between controllers, sensors, and host systems. Equipped with an onboard SD card slot and a CR2032 backup battery, it supports real-time data logging and maintains system clock integrity even during power interruptions. The board features robust galvanic isolation on its communication transceivers, ensuring stable and reliable operation in electrically noisy industrial environments.

Industrial Automation & Control – Serves as a versatile communication bridge for PLCs, industrial PCs, and field devices. It enables seamless data acquisition and control commands across CAN, RS485, and Ethernet networks, streamlining integration in factory automation and process control systems.

CAN Bus Networking – Provides a reliable physical layer for CAN bus communication, making it ideal for connecting motor controllers, sensors, and actuators in automotive, mobile machinery, and embedded control applications. The isolated transceiver protects the main processor from voltage spikes and ground loops.

RS485 Serial Communication – Supports long-distance, multi-drop serial communication for Modbus RTU and other industrial protocols. This makes the board suitable for connecting remote I/O modules, meters, and legacy equipment to a central management system.

Ethernet Connectivity & Cloud Integration – The onboard RJ45 port allows direct connection to local area networks (LAN), enabling remote monitoring, configuration, and data upload to cloud platforms or SCADA systems. High-speed Ethernet ensures timely transmission of large data volumes.

Real-Time Data Logging & Backup – The integrated SD card slot facilitates local storage of operational logs, sensor readings, and diagnostic data, which can be retrieved for analysis. The CR2032 battery maintains the real-time clock (RTC) and preserves critical system settings during power outages.

Robust Isolation & Noise Immunity – Galvanic isolation on the CAN and RS485 channels prevents ground loops and protects sensitive electronics from high-voltage transients. This design ensures reliable communication and extended service life in harsh electromagnetic environments common to industrial and outdoor installations.
