Yokogawa Optical ESB Bus Repeater Slave Module SNT501[Product print page]

Yokogawa Optical ESB Bus Repeater Slave Module SNT501

The Optical ESB Bus Repeater Module converts ESB Bus, which connects safety control unit (SSC60S/SSC60D, SSC50S/SSC50D, SSC10S/SSC10D) and safety node unit (SNB10D), to optical signal.

ESB Bus transmission distance can be extended by connecting Optical ESB Bus Repeater Master Module (SNT401) and Optical ESB Bus Repeater Slave Module (SNT501) with an optical fiber cable.

In case Vnet/IP is adapted as a control network, it is possible to use both Optical ESB Bus Repeater Master Module

(SNT411) and Optical ESB Bus Repeater Slave Module (SNT511)

SNT401 Optical ESB Bus Repeater Master Module

This module is connected from ESB Bus Coupler Module (SEC401, SEC402) on the safety control unit or ESB Bus

Interface Module (SSB401) on the safety node unit (SNB10D) through ESB Bus cable.

There are two types of ESB Bus Repeater Modules: with or without a terminator.

SNT501 Optical ESB Bus Repeater Slave Module

This module is connected from Optical ESB Bus Repeater Master Module through fiber-optic cable. Furthermore, it is connected through ESB Bus cable to ESB Bus Interface Module (SSB401) on the safety node unit (SNB10D).
