Product Description

The ARM55D-00 is a high-density mechanical relay output board engineered for the Yokogawa CENTUM VP and CS 3000 distributed control systems. This module provides 32 independent dry contact outputs, utilizing "a" (normally open) contacts to facilitate the switching of field devices such as motors, solenoids, and heavy-duty actuators.

The ARM55D-00 (Model: ARM55D-00) is a critical interface component that provides robust physical isolation between the sensitive DCS logic and the electrical noise of the field environment. Designed for high-availability infrastructures, it supports both single and dual-redundant configurations, ensuring that critical control loops remain operational even during a hardware swap.

The board features heavy-duty M4 screw terminals for field wiring, providing secure and vibration-resistant connections. Its standard 19-inch rack-mountable form factor allows for seamless integration into industrial control cabinets, optimizing space while maintaining accessible cable management.

Application and System Role

The ARM55D-00 serves as a power-marshalling interface. It is typically connected to digital output modules (such as the ADV551) via signal cables, translating the low-level system signals into robust contact closures capable of handling higher field currents.

This makes it an ideal solution for power plants, oil refineries, and water treatment facilities where large-scale discrete equipment must be controlled
