AMN32 | Yokogawa Nest for Connector I/O Module

Product Overview

The Yokogawa AMN32 is an I/O Module Nest for Connector-Type I/O Modules in the CENTUM CS/VP RIO system. It accommodates digital and multiplexer modules with connector-type wiring (KS cable interface), providing a compact, high-density solution for applications requiring quick disconnect and reduced wiring time. The AMN32 is ideal for installations with frequent module changes or space-constrained cabinets.

FAQ

• Q: What is the advantage of connector-type over terminal-type?
  A: Connector-type modules allow faster installation and replacement using KS cables, reducing wiring time and maintenance downtime.
• Q: What KS cables are required?
  A: KS2, KS3, KS9, or KS10 cables depending on the module type; consult Yokogawa wiring manuals for specific cable selections.
• Q: Can terminal-type modules be used in AMN32?
  A: No, AMN32 is specifically for connector-type modules; use AMN31 for terminal-type modules.
• Q: Is AMN32 suitable for hazardous areas?
  A: The nest itself is not rated for hazardous areas; use appropriate barriers or intrinsically safe modules for such applications.

Selection Tips

• Choose AMN32 for high-density digital or multiplexer applications where quick module replacement is prioritized.
• Ensure compatible KS cables and terminal boards are ordered with the nest for complete installation.
• Consider AMN31 for terminal-type modules if direct M4 screw wiring is preferred.
