Product Description
The ARM55D-000 is a high-capacity relay output board engineered by Yokogawa for reliable switching in industrial control environments. The board provides 32 individual mechanical relay channels, each configured as a dry contact (“a” contact / Normally Open) output. It is designed for systems that require high-density discrete signal distribution to field devices such as actuators, alarms, and signaling equipment.
The ARM55D-000 supports both single and dual-redundant system configurations, ensuring high availability and operational reliability. Designed for installation in standard control cabinets, the board features M4 screw terminals that provide secure and vibration-resistant field wiring connections. This robust construction ensures stable signal switching and long-term durability in demanding process automation environments.

Technical FAQ
Is the ARM55D-000 suitable for high-current loads?
The ARM55D-000 uses mechanical relay dry contacts for switching. The connected load must remain within the relay current and voltage ratings specified in the Yokogawa system documentation to prevent contact wear or premature relay failure.
Can this board be used in dual-redundant control systems?
Yes. The ARM55D-000 is designed to support both single and dual-redundant architectures, making it suitable for high-reliability control systems where continuous operation is critical.
