Description：
DIN-Rail 1-8 Channel Fiber Optic Aggregation Multiplexer 8-Channel Fiber Optic Aggregation Switch I/O Terminal Equipped with 8 SC/FC/LC fiber optic modules, this device can connect up to 8 optical directions. It is available in two types: a central aggregation unit and a node unit. The aggregation end supports a total of 16 discrete I/O interfaces, or alternatively, Modbus RTU/TCP protocols. When outputting physical discrete I/O signals, the node unit provides up to 1-2 channels. When using Modbus RTU or Modbus TCP, it supports up to 1-16 channels of discrete I/O (which can be configured as either inputs or outputs). The units are interconnected via fiber optic cables. This product effectively solves challenges such as electromagnetic interference (EMI), ground loops, and lightning damage, significantly improving the reliability, security, and confidentiality of data communication. It is widely used in various industrial, process, and traffic control applications. It is particularly suitable for industrial and power sectors, as well as systems with strict requirements for environments with high electromagnetic interference.
Description：
Modular DIN-Rail Intelligent 1-to-4 RS485 Isolated Hub This 4-channel RS485 isolated hub features 1-to-4 fully electrically isolated RS485 channels. Each RS485 channel is equipped with 6kV lightning protection, optoelectronic isolation with an isolation voltage of up to 3kV, and an independent ground. This design ensures that if one RS485 bus is damaged, the devices on the other buses remain fully protected. Each RS485 port supports up to 128 nodes, and the power port also features 6kV lightning protection. The device includes built-in functions for detecting and isolating line short circuits and data errors. Equipped with common-mode choke differential filtering and an FPGA digital filter, it supports a communication distance of up to 2200 meters (at 9600 bps). It is widely used in complex industrial systems.
