Overview

The Yokogawa SNT401-53 Optical ESB Bus Repeater Master Module extends the communication range of the ESB Bus within the ProSafe-RS safety system. It enables stable optical signal transmission across distances up to 10 km, depending on configuration. By pairing with the SNT501-53 slave module, it supports both star and chain-type topologies for safety controller and node connectivity.

Function and Compatibility

• Primary Function: Extends ESB Bus communication using optical signal transmission.
• Compatibility: Works with safety control units such as SSC10S/D, SSC50S/D, SSC60S/D, S2SC70S/D, and node units like SNB10D.
• Connection Requirements: Connects from ESB Bus Coupler Modules SEC401/SEC402 or ESB Bus Interface Module SSB401 via ESB Bus cables.
• Types Available: With or without a terminator, depending on installation needs.
