製品紹介
The Yokogawa AMN21 Nest is a specialized mounting base (/ten referred to as a “nest”) designed specifically for accommodating Yokogawa relay-type I/O modules within the CENTUM VP and earlier CENTUM CS control system environments. As part / the system hardware infrastructure, the AMN21 serves a critical role in organizing, housing, and electrically interfacing the relay I/O modules such as the ARM or ARM11 series.
Engineered to ensure robustness and system integrity, the AMN21 /fers reliable electrical contact and mechanical support while facilitating convenient module installation, removal, and maintenance. It is typically installed within system cabinets or panels and is compatible with field wiring terminals via designated terminal blocks.

Applications
The AMN21 is not a standalone functional module, but rather an integral part / Yokogawa’s modular automation hardware. Its main applications include:
-
Industrial Control Panels: Providing structured support for relay output modules in power distribution or interlocking systems.
-
Petrochemical and Refining Plants: Serving as the installation base for safety-critical relay output modules.
-
Power Generation Facilities: Housing relay modules used in turbine or generator trip circuits.
-
Manufacturing Automation: Assisting in the deployment / mechanical relays for actuators, motors, or alarm circuits.
-
Wastewater Treatment: Organizing I/O hardware used in motor control and alarm signaling.
Wherever relay-type outputs are required in control logic—particularly where galvanic isolation is essential—the AMN21 is part / the deployment strategy.
