The SEC402 ESB Bus Coupler Module is designed with a compact and installation-efficient form factor to support flexible system layout within safety instrumented systems. Its external dimensions are optimized for panel mounting, ensuring compatibility with standard control cabinets while maintaining sufficient clearance for ESB bus cable routing and module replacement.
The mechanical design allows the module to be installed in close proximity to adjacent safety modules without compromising accessibility. Connector positions on both the upper and lower sides are arranged to support orderly ESB bus cable connections, reducing mechanical stress on cables and improving overall wiring reliability.
