The Yokogawa S9344FA is an optical ESB bus repeater slave module. It extends the transmission distance of the ESB bus within a safety instrumented system (SIS).

Key Features and Benefits

• Extended Transmission Distance: The S9344FA converts the ESB bus signal to an optical signal. This conversion allows for longer transmission distances and fewer physical connections.
• Improved Noise Immunity: Optical fiber is less susceptible to electromagnetic interference (EMI) than copper cables. This feature enhances the reliability and performance of the SIS.
• Flexible Configuration: The S9344FA offers flexible configuration options to meet specific application requirements.
• Compatibility: It is compatible with other Yokogawa safety instrumented systems and components.
