EtherNet/IP Backplane Integration Characteristics
The 1444-TB-A supports backplane bus communication velocity licenses through direct local bus interconnection between Dynamix 1444 monitoring modules. Mechanical alignment tolerances and terminal spacing are designed for deterministic module insertion and stable EtherNet/IP communication continuity. The terminal base architecture permits I/O density scaling without additional external junction assemblies.
Frequently Asked Questions (FAQ)
Q: Can Dynamix 1444 modules operate without the 1444-TB-A terminal base?
A: No. The terminal base is required for module mounting, power distribution, and field termination.
Q: What type of power supply is permitted for this terminal base?
A: The unit supports 18–32 V DC SELV/Class 2 power supplies with a maximum current capacity of 5 A.
Q: Is the terminal base hot-swappable during operation?
A: Removal or insertion under energized conditions is not recommended because bus communication and field wiring continuity may be interrupted.
Field Installation Guidelines
-
Secure the terminal base firmly to a grounded DIN-35 rail before module installation.
-
Verify all screw terminal torque values according to field wiring practices to prevent intermittent contact faults.
-
Separate low-level signal wiring from high-current motor and relay conductors.
-
Install the 1444-TBA-RPC connector set before applying system power.
-
Maintain enclosure airflow to avoid localized thermal accumulation around terminal assemblies.
