MTL PAC8000 System 8937-HN Fiber Optic Expander Module.
MTL 8937-HN belongs to the fiber optic extender module in the PAC8000 system. 8937-HN is used for converting electrical signals between PAC8000 I/O bus and fiber optic signals, extending the communication distance between PAC8000 nodes and controllers through fiber optic cables, and avoiding electromagnetic interference caused by long-distance copper cables.

Main function:
- Complete the bidirectional conversion of PAC8000 system I/O Link electrical signals and fiber optic optical signals to achieve optoelectronic isolation;
- Extend the communication distance of PAC8000 bus using fiber optic media to solve the problem of long distance between the controller and remote I/O nodes;
- Electrical isolation on both sides of the bus, blocking ground loop interference and surge interference, and improving communication stability in harsh environments on site;
- Support point-to-point fiber optic links, which can be used in pairs (local end+remote end) to build long-distance I/O bus links;
- Panel LED status indicator light, providing feedback on power, transceiver, and link fault status for easy troubleshooting;
- As a spare part, it is used for replacement and repair of damaged PAC8000 system hardware in stock.
Main product range
- Control system (DCS/PLC/CNC): panel controller, HMI and human-machine interface, industrial PC, CPU processor module, communication module, analog/digital I/O module
- Drive and motion control: frequency converter, servo drive, servo motor, power module
- Robot spare parts: key spare parts such as robot control board, axis computer, servo unit, I/O module, etc
- State monitoring and safety system: vibration monitoring system, safety instrumented system (SIS), redundant controller
