Product Overview
The Yokogawa ARM15A (SARM15A) functions as a high-performance Mechanical Relay Contact Input Module within the CENTUM VP distributed control system. It captures discrete signals from field devices such as pressure switches, limit switches, and push buttons, converting physical contact states into digital signals for the system processor. This module ensures reliable signal acquisition and system integrity in demanding industrial environments. We supply this unit as 100% brand new, original hardware manufactured in France.

Engineering Advantages
Superior Noise Immunity
Mechanical relay-based input design provides strong galvanic isolation, effectively protecting the control system from electromagnetic interference (EMI) and electrical noise.
Ultra-Lightweight Design
With a weight of only 0.1 kg, the module reduces mechanical load on the I/O backplane and simplifies handling during installation or replacement.
Direct Field Interfacing
Supports direct connection of dry contact inputs, eliminating the need for additional signal conditioning or interposing relays, thereby reducing wiring complexity.
Optimized Space Utilization
The compact 7.6 cm width enables high-density I/O configurations, allowing more channels to be installed within limited cabinet space.
FAQs
What is the difference between ARM15A and SARM15A?
The “S” prefix typically indicates a revision or internal classification. Functionally, both refer to the same mechanical relay input module for CENTUM VP systems.
Can this module monitor active voltage signals?
No, it is designed for dry contact (potential-free) inputs only. Applying voltage directly may damage the module.
How does the module indicate a channel state change?
Each input channel has an LED indicator. When the contact closes, the corresponding LED illuminates, providing immediate visual feedback.
Is this module compatible with hot-swap procedures?
Yes, it supports hot-swapping within the CENTUM VP system, allowing replacement without shutting down the entire I/O node.
