Allen-Bradley 1444-DYN04-01RA Dynamic Measurement Module

The Allen-Bradley 1444-DYN04-01RA serves as the primary 1444-DYN04-01RA Dynamic Measurement Module utilized to execute real-time vibration, strain, pressure, and shaft position acquisition across Dynamix 1444 monitoring platforms.

Hardware Specifications

Deterministic EtherNet/IP Communication Architecture

The 1444-DYN04-01RA supports Profinet / EtherNet/IP deterministic networks for synchronized machine condition monitoring within Logix-based control systems. Internal firmware architecture permits autonomous relay-based protection execution even during controller communication loss. The module supports scalable I/O density expansion through Dynamix 1444 auxiliary modules including tachometer, relay, and analog output interfaces.

Frequently Asked Questions (FAQ)

Q: Does the module continue machinery protection if the Logix controller becomes unavailable?
A: Yes. Protection functions execute locally through internal relay logic independent of controller communication status.

Q: Is the 1444-TB-A terminal base mandatory for installation?
A: Yes. The module requires the 1444-TB-A terminal base for physical mounting and electrical termination.

Q: Can the module operate with standalone EtherNet/IP communication?
A: EtherNet/IP connectivity is required for configuration, diagnostics, and integration into the Logix architecture, while local protection functions remain active independently.

Field Installation Guidelines

• Install the module only on the designated 1444-TB-A terminal base assembly.

• Route vibration and low-level analog signal wiring separately from motor power conductors.

• Ground cable shields at a single designated panel grounding point to minimize induced noise.

• Verify EtherNet/IP network segmentation and switch configuration before commissioning.

• Maintain adequate enclosure airflow to prevent thermal accumulation around relay and processing sections.
