126B/126D Industrial Serial Data Optical Transceiver

Product catalog summary

Product Overview: The AOBO 126B/126D series are industrial self-healing loop data optical transceivers designed for robust optical fiber communication. They serve as master or slave station equipment in networking applications, supporting up to 128 stations per loop and allowing 6 to 10 serial channels for simultaneous communication. These devices are suitable for harsh environments, offering wide temperature range operation, electromagnetic interference resistance, and over-voltage protection.

Performance Parameters: The transceivers feature two optical ports with options for single or multimode, and support various serial ports (RS232, RS422, RS485) with an asynchronous rate of up to 230.4 KBPS. They include line surge and ESD protection, with transmission distances varying by port type: RS232 up to 15M, RS422/RS485 up to 1200M, and optical fiber up to 80KM.

Model Specifications: Multiple configurations are available, including options with ABPass® light path protection. Models vary by the number of serial data interfaces and optical interfaces, with specific configurations for different installation and power supply needs.

Power Supply and Mechanical Structure: The devices support a wide input voltage range with redundancy and overload protection. They feature a metal enclosure with IP30 protection, designed for rail-type installation, and operate without a fan.

Environmental and Quality Standards: Operating and storage temperatures range from -40℃ to +85℃, with a relative humidity tolerance of 0-95%. The devices comply with various EMI and EMS standards, ensuring high reliability with an MTBF of 800,000 hours and a 5-year warranty.

Industry Standards: The transceivers meet several international standards for electromagnetic interference, electrostatic discharge, and mechanical resilience, ensuring robust performance in industrial settings.

OBO 126B/126D Industrial Self-healing Loop Serial Data Optical Transceiver • Support the selection of RS485/RS232/RS422/TTL fiber interface? Allow the selection of the ABPassf® light path protective module? • Provide the inbuilt ABRin^f distributed high self-healing loop network protocol and link switching of the seif-healing loop without the packet loss? • Support the access from any station and realize the iManager network management function, equipment configuration, status inquiry and alarm function? • Support the function of the port data mirroring and facilitate the system maintenance and debugging? • Support the RS485 line fault protection. AOBO 126B/126D series of industrial self-healing loop data optical transceiver are a type of the self-healing loop serial optical fibre communication equipment. In the application networking, a set of AOBO 126B/126D equipment is used as the master station equipment. One or more AOBO 126B equipment is considered as the standby master station equipment or slave station equipment. The number of station equipment in each self-healing loop network may reach 128 at most; a maximum of 6 (or 10) serial channels are allowed to be set between the equipment of the master and slave stations to attain the simultaneous communication. AOBO 126B series support the wide temperature range (-40°C~+85°C), strong resistance to electromagnetic interference, over-voltage protection, 24VDC redundant double power input, DIN rail and wall mounting and are capable of operating stably under the adverse industrial environment. AOBO 126B/126D series of industrial selfhealing loop serial data optical transceiver can be widely applied to the road monitoring and other scenarios needing the data acquisition, such as the electronic monitoring data acquisition and industrial process control.
