Description

The S9981DE-01 is a YOKOGAWA back plane designed for integration with industrial control systems, specifically aligned with the brand’s S900 I/O product line. As a passive back plane, it supports internal bus communication for field circuits, data transfer, and power distribution, serving as a foundational mounting platform for functional modules. It is compatible with DIN rail or direct mounting on distribution boards, and features dedicated slots for power modules, communication interface modules, and functional I/O modules. Redundant configurations of this back plane include 2 power slots, 2 communication interface slots, and 16 functional module slots, enabling connection of up to 128 digital channels or 64 analog channels per station when paired with compatible modules (8-channel digital modules, 4-channel analog modules). It supports use in hazardous and non-hazardous areas: S-series configurations are for Zone 1 hazardous areas, B-series for Zone 2 hazardous areas, and N-series for non-hazardous areas, with ATEX-certified installation options for Zone 1 wall and field mounting. Key features include seamless integration with 800xA process control systems via FDT/DTM or GSD files, and support for hot-swappable components to enhance system availability, along with cost-efficiencies from reduced wiring, installation, and maintenance requirements.
