Product Description

The AMN32-S1 is a high-integrity I/O module nest engineered for Yokogawa CENTUM CS and CENTUM VP systems. Designed as a standard 19-inch rack-mount unit, it serves as the physical and electrical backbone for housing AMM and AAM series I/O modules within control cabinets.

Beyond mechanical support, the AMN32-S1 provides backplane communication and power distribution, ensuring multiple modules operate seamlessly together. Built to industrial standards, it offers vibration resistance, thermal dissipation, and organized wiring paths for KS1/KS2 or other Yokogawa-compatible signal cables, simplifying field wiring and maintenance. This rack is ideal for scaling I/O capacity in distributed control environments while maintaining system reliability.

Technical Specifications

Application Scenarios

• DCS Expansion
  Increase the I/O channel count of CENTUM VP Field Control Stations by adding module nests in remote or central cabinets.

• Signal Marshaling
  Centralize field wiring from thermocouples, RTDs, and 4–20 mA transmitters into a single organized rack.

• Legacy System Upgrades
  Provide a stable platform for modern AMM/AAM modules when retrofitting older signal conditioning systems.

Product FAQ

Q: Does the AMN32-S1 include the I/O modules?
A: No. The AMN32-S1 is the base rack assembly only. I/O modules (e.g., AMM22C, AAM50) must be purchased separately according to channel requirements.

Q: How is the module nest powered?
A: Power is supplied through the internal backplane, which interfaces with the system’s 24 V DC supply to energize all inserted I/O modules.
