Product Description
The SEC401-11 S2 is an ESB (Extended Safety Bus) master interface module for the Yokogawa ProSafe-RS. It enables high-speed communication between the central safety control station and remote safety node units.
By managing deterministic data exchange across distributed I/O nodes, the module ensures synchronized safety logic execution and reliable signal transmission. This makes it a key component for emergency shutdown (ESD) and other safety-critical control functions in hazardous industrial environments.

FAQ
What does the “S2” suffix mean?
The S2 designation typically indicates a newer hardware revision with improved diagnostics and enhanced reliability for modern SIL-compliant safety systems.
Can the ESB cable length exceed 10 meters?
No. The ESB bus architecture limits the total cable length to 10 meters. For longer distances, alternative communication solutions or fiber-based extensions within the Yokogawa ProSafe-RS architecture are required.
