YOKOGAWA EC402-50 S1 ESB Bus Coupler Module
The YOKOGAWA EC402-50 S1 is an ESB Bus Coupler Module designed for Yokogawa's Field Control Units (FCUs) for FIO (Field Input/Output) systems. Function:Connects the Field Control Unit to Node Units within the Yokogawa ESB (Electronic Serial Bus) network.Enables communication between the FCU and various I/O devices like sensors and actuators on the ESB bus.Features:Dual Redundancy Support: The "S1" suffix in the model number might indicate compatibility with Yokogawa's redundancy configurations. By installing two EC402-50 S1 modules in an FCU, a redundant ESB bus can potentially be formed, ensuring continued operation even if one module fails.Extended Network Reach: Compared to the earlier Yokogawa EC401 module, the EC402 series is said to offer a longer transmission distance on the ESB bus, allowing for connecting more nodes to the network.Applications:Primarily used in Yokogawa's FIO-based industrial automation systems, particularly for:Process control applications in various industri
