EMC type all metal suitable for analog junction boxes

This module includes 8 RS485 main/IO ports, which can be configured and used independently of each other. All RS485 ports support COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8 ports, and SI0 modes. In the 8 ports of the main station, 485 communication function or IO function can be selected. If there are enough local functional devices and the main station ports cannot provide sufficient signal control, RS485 communication function can be selected to expand the main station module and attach sub stations to meet the actual needs.
