Product Description
The ANT401-50/CU1T is a high-performance Optical ESB Bus Repeater Master Module developed by Yokogawa for the CENTUM VP and ProSafe-RS control systems. Designed to extend the distance of ESB (Enhanced Safety Bus) communication, it converts electrical signals into optical signals, enabling high-speed, noise-immune transmission up to 5 km. As a "Master" module, it is installed on the Field Control Unit (FCU) side to initiate the optical link to remote node units.

Industrial Application Scenarios
The ANT401-50/CU1T is ideal for:
-
Offshore oil & gas platforms, chemical plants, and large refineries
-
Remote I/O networks, where node units are kilometers from the central control room
-
High-voltage or outdoor environments, offering total immunity to lightning strikes and electromagnetic interference (EMI)
The /CU1T connector unit with integrated terminator ensures signal integrity at the end of the local ESB bus segment, maintaining reliable communication for safety-critical loops.
Technical FAQs
1. What is the difference between a Master (ANT401) and a Slave (ANT502) module?
The ANT401 (Master) initiates the optical signal from the FCU, while the ANT502 (Slave) receives it at the remote node. Both must be used together to form a functional optical ESB link.
2. What type of optical fiber is required?
Typically, multi-mode fiber (MMF) is used. For distances up to 5 km, ensure the fiber meets Yokogawa’s attenuation specifications to prevent signal loss.
