YOKOGAWA ANT401-50CU1N

The YOKOGAWA ANT401-50CU1N is a high-performance industrial optical ESB bus repeater master module designed for Yokogawa CENTUM VP distributed control systems (DCS). Engineered to extend ESB bus communication distances and enhance industrial network stability, this module serves as a core component for long-distance signal transmission in process automation scenarios, widely applied in petroleum, chemical, power generation, and manufacturing industries.

Featuring reliable optical signal conversion capabilities, the YOKOGAWA ANT401-50CU1N efficiently converts electrical ESB bus signals into optical signals to eliminate electromagnetic interference (EMI) and signal attenuation issues in long-distance transmission. Paired with the ANT502 slave module, it supports a maximum transmission distance of 5 km, perfectly meeting the layout demands of large-scale and scattered industrial control sites.

This module boasts professional technical parameters for industrial-grade stability. It adopts a 2-port design, supporting flexible chain and star network topologies to adapt to diverse cabinet and field layout requirements. The standard power supply is 5V DC with a rated working current of 0.5A and total power consumption below 5W, achieving low-energy operation without compromising transmission efficiency. It allows up to 2 cascaded stages in chain connection and supports 8 connected nodes for stable multi-device networking.

In terms of environmental adaptability, the YOKOGAWA ANT401-50CU1N operates steadily in temperatures from 0°C to 55°C and 10%–90% non-condensing humidity, suitable for harsh industrial environments. With compact dimensions of 142.5×130×32.8mm and a net weight of 0.25kg, it supports standard DIN rail mounting for quick, space-saving installation. It also supports dual-redundant configuration to avoid network interruption, greatly improving system operational safety.

As an original Yokogawa industrial communication module, the ANT401-50CU1N features anti-interference, high transmission accuracy, and long service life. It effectively optimizes DCS bus transmission performance, extends control network coverage, and reduces system maintenance costs, making it an ideal upgrade and replacement solution for industrial automation ESB bus systems.
