Table 1 Software Version

 OVERVIEW

SG485-3 is the expansion module of the RS485 interface, which has 3 interfaces, namely the RS485 host interface, RS485 slave 1 interface, and RS485 slave 2 interfaces. It can convert 1# RS485 interface to 2# RS485 interface, providing convenience for customers to monitor and collect data via Modbus-RTU protocol.

PERFORMANCE AND CHARACTERISTICS

Its main characteristics are as follows:
─ With 32-bit ARM SCM, high hardware integration, and improved reliability;
─ DC(8~35)V continuous power supply;
─ 35mm guide rail installation method;
─ Modular design and pluggable connection terminals; compact structure with easy mounting.
