OVERVIEW

SG485-2CAN is a communication interface conversion module, which has 4 interfaces, namely RS485 host interface, RS485 slave interface and two CANBUS interfaces. It is used to convert 1# RS485 interface to 2# CANBUS interfaces and 1# RS485 interface by DIP switch to set address, providing convenience for customers to monitor and collect data.

PERFORMANCE AND CHARACTERISTICS
Its main characteristics are as follows:
─ With 32-bit ARM SCM, high hardware integration, and improved reliability;
─ 35mm guide rail installation method;
─ Modular design and pluggable connection terminals; compact structure with easy mounting.
