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

Configured for precision signal acquisition in Dynamix platforms, the Allen-Bradley 1444-DYN04-01RA (1444-DYN04-01RA Dynamic Measurement Module) provides direct physical and electrical execution of 4-channel dynamic sensing and control signal integration.

Hardware Specifications

Industrial Control and Deterministic Networks

The 1444-DYN04-01RA utilizes Ethernet communication to facilitate data exchange within industrial control networks. The module supports I/O density scaling through modular expansion within the Dynamix system, ensuring that multi-channel dynamic measurement requirements are met with deterministic timing. Firmware flash compatibility is critical for maintaining alignment with host controller scan cycles and ensuring that signal processing algorithms remain current. The integration of 2 digital outputs and 1 relay output allows for immediate local control actions based on real-time dynamic data analysis.

Frequently Asked Questions

Q: Can the relay output be used for safety-rated interlocking?

A: No. The relay output on the 1444-DYN04-01RA is a standard control relay and is not certified for functional safety (SIL) applications. It should only be used for monitoring or non-safety-critical control tasks.

Q: How is the module mounted for optimal signal integrity?

A: The module must be installed on a 35 mm DIN rail. To minimize electromagnetic noise and maintain signal integrity for dynamic inputs, ensure the DIN rail is securely bonded to a low-impedance earth ground.

Field Installation Guidelines

• Mounting: Snap the module onto a 35 mm DIN rail in a vertical orientation to ensure proper convective cooling. Maintain the specified altitude limits (up to 1000 MSL) to ensure thermal dissipation performance as per the datasheet.
• Wiring: Utilize shielded twisted-pair cabling for dynamic input signals to minimize electromagnetic interference (EMI). Connect shield drain wires to the designated terminal ground points to prevent noise coupling.
• Power Supply: Connect to a stable 32 VDC (max) power source. Ensure the voltage is within the specified operating range to prevent damage to the module electronics.
• Environmental Sealing: The module is designed for an operating range of -25 to 70 deg C in non-condensing environments. Install within a cabinet rated at least IP54 if the operating environment contains dust or moisture to protect the terminal connections.
