Yokogawa ARM15A-000 CENTUM VP FIO 32-Point Relay Board

Product Overview

The Yokogawa ARM15A-000 serves as a high-density 32-point relay board specifically engineered for the FIO (Field Interface I/O) subsystem of the CENTUM VP Distributed Control System (DCS). This board functions as the critical physical interface between digital I/O modules and field-side equipment, facilitating clean signal transmission, isolation, and amplification. It supports 32 dry contact inputs, allowing the DCS to monitor field statuses with absolute precision. We supply this unit as 100% Brand New and Original, ensuring your industrial control loops operate with factory-spec performance and long-term stability.

Engineering Advantages

The ARM15A-000 resolves common field integration challenges through superior electrical and physical design:

• High-Voltage Galvanic Isolation: The board provides 1.5 kV isolation between field-side wiring and the DCS case. This prevents ground loops and high-voltage surges from damaging the Field Control Station (FCS), protecting your core automation investment from unpredictable field faults.

• Secure Industrial Termination: The integration of M4 screw terminals ensures high-torque, vibration-resistant connections. This hardware choice prevents accidental signal loss in high-vibration environments, such as those found near heavy compressors or turbines.

• Dual-Redundant Architecture Support: The internal circuitry fully supports dual-redundant I/O configurations. If one communication path fails, the system maintains continuous signal flow through the secondary path, ensuring zero downtime for critical monitoring loops.

• Simplified Signal Amplification: By acting as an intermediary, the ARM15A-000 amplifies weak field signals before they reach the digital input modules. This ensures the DCS accurately interprets dry contact states over longer cable distances without signal degradation.

FAQs

• What type of field wiring does the ARM15A-000 accommodate?

  The board utilizes M4 screw terminals, which accept standard ring or spade lugs. This allows for clean, organized cable management within the control cabinet and ensures a gas-tight electrical connection.

• Can I use the ARM15A-000 in a redundant FIO setup?

  Yes. This board supports dual-redundant compatibility. When connected to redundant digital I/O modules, it facilitates seamless failover without interrupting the process monitoring status.

• Does this board require an external power source?

  The internal logic circuit requires a 24 V DC supply (drawing a maximum of 0.3 A). The DCS backplane typically provides this power, but you should verify your cabinet's power distribution plan to ensure adequate current overhead.

• Is this a "New Surplus" or "Refurbished" item?

  We offer this unit as 100% Brand New and Original. It ships in its original Yokogawa factory packaging, featuring the authentic manufacturer's label and full serial number traceability.
