Product Description

The AMN21 is a high-performance base rack nest engineered for the secure mounting and integration of relay I/O modules within Yokogawa industrial automation systems. Serving as both a mechanical and electrical backbone, the AMN21 ensures reliable signal processing for discrete control and safety applications.

Built for durability and compactness, this rack provides organized module management, vibration-resistant backplane connectivity, and stable support for relay logic. It is ideal for power distribution, motor control, and interlocking safety circuits, delivering professional-grade performance in industrial control cabinets.

Technical Specifications

Application Scenarios

• Discrete Control Systems
  Centralized housing for relay modules controlling solenoid valves, motor starters, and other on/off devices.

• Safety Interlocking
  Supporting relay interfaces for emergency shutdown (ESD) and other protective control circuits.

• Signal Isolation
  Physically isolates high-voltage field relay signals from sensitive low-voltage control logic.

Product FAQ

Q: Does the AMN21 include the relay modules?
A: No. The AMN21 is the base rack only. Relay I/O modules must be ordered separately to populate the nest.

Q: Can this rack hold non-relay modules?
A: No. The AMN21 is specifically keyed for relay I/O modules. For standard analog or digital modules, use an alternative nest such as the AMN32 series.
