1444-TSCX02-02RB | Allen-Bradley | Dynamix Tachometer Signal Conditioner Expansion Module

Configured for speed signal processing in Dynamix platforms, the Allen-Bradley 1444-TSCX02-02RB (1444-TSCX02-02RB Tachometer Signal Conditioner Expansion Module) provides direct physical and electrical execution of speed signal conditioning via the 1444 series local bus.

Hardware Specifications

Firmware and Backplane Communication

The 1444-TSCX02-02RB functions as a specialized expansion node requiring connection to a parent Dynamix dynamic measurement module for backplane bus communication. Deterministic operation is achieved through the 1444 series local bus, which synchronizes speed data with the primary measurement module. Firmware flash compatibility is managed via the host module to ensure that signal conditioning algorithms and TTL output timing remain consistent with system-wide measurement parameters and I/O density scaling requirements.

Frequently Asked Questions

Q: Can the 1444-TSCX02-02RB operate as a standalone tachometer module?

A: No. The expansion module requires a primary 1444 series dynamic measurement module to function. It lacks independent network connectivity and power management features, relying entirely on the parent module for system integration.

Q: Are the TTL speed outputs electrically isolated?

A: The outputs are designed for standard TTL logic levels. Users must verify common ground references between the expansion module and the destination device to prevent ground loop interference on the speed signal lines.

Field Installation Guidelines

• System Integration: Mount the module adjacent to the parent dynamic measurement module. Ensure the local bus connector is fully seated to maintain signal continuity between modules.
• Terminal Base Requirement: Installation requires the use of the specified 1444 series terminal base (B) and removable plug connectors. Verify that connectors are fully locked to prevent intermittent connection failures.
• Shielding: Route input speed signals through shielded twisted-pair cabling. Connect the shield drain wire to the designated chassis ground on the terminal base to mitigate electromagnetic noise.
• Mechanical Stability: Ensure the module is secured on a 35 mm DIN rail. In high-vibration environments, verify that the module retention clips are locked to avoid loosening of the local bus electrical contacts.
