Yokogawa Electric Corporation AED5D-06 Terminal Board for Digital

The Yokogawa AED5D-06 Terminal Board for Digital is a 32-channel field-wiring interface that terminates digital I/O signals for Yokogawa CENTUM VP DCS cabinets and marshalling panels, enabling structured signal routing for digital input and output modules. It supports single- and dual-redundant configurations to improve reliability and is compatible with ADV151, ADV551, ADV161, and ADV561 modules via system cables, providing a direct interface between field devices such as switches, relays, and actuators and DCS I/O modules. The board uses M4 screw terminals, mounts on panel/marshalling-panel installations, and offers insulation resistance of ≥100 MΩ at 500 VDC and a withstand voltage of 500 VAC for 1 minute, with a corrosion-resistant G3 option available and an approximate weight of 1.5 kg.
