The Optical ESB Bus Repeater Module converts standard ESB Bus signals—which interconnect the Safety Control Unit, Safety Node Unit, and N-IO Node—into optical signals. This conversion enables extended transmission distances without signal degradation. By utilizing optical fiber connections between modules, the communication range of the ESB Bus can be significantly increased.
Extended Distance Configuration
Optical ESB Bus Repeater Master Module
Optical ESB Bus Repeater Slave Module
SNT401
SNT501
Applications
The Optical ESB Bus Repeater Module is ideal for applications requiring long-distance, high-reliability communication in industrial and safety-critical environments:
Distributed safety control systems in manufacturing plants
Process automation systems with geographically separated nodes
Remote monitoring and control in chemical, oil & gas, or power plants
Industrial networks where traditional copper ESB Bus distance limitations are exceeded
Integration of safety nodes across large facilities while maintaining fast and secure communication
Nominal Tolerances
When the reference dimension is over 0.5 mm and equal or less than 120 mm, its nominal tolerance is ± 0.8 mm, while its combination of nominal tolerance is ± 1.5 mm. When the reference dimension is over 120 mm, its nominal tolerance is in accordance with JEM 1459.
The Optical ESB Bus Repeater Module supports flexible connection topologies to accommodate various industrial and safety system layouts. Two primary connection structures are commonly used: Chain Type and Star Type.
Chain Type Connection
For chain type configurations, there are two main approaches:
Direct Mounting: Optical modules are installed directly on the Safety Control Unit and Safety Node Unit.
Dedicated Mounting: Optical modules are installed on the dedicated SNT10D Unit (Unit for Optical Bus Repeater Module).
These two approaches can also be combined within the same chain, offering flexibility in system design while maintaining reliable ESB Bus communication over extended distances.
We understand that in this industry, reliability is everything. That's why at Amikon, we focus on the five things that matter most to you:
