Industrial Control Bus and I/O Interface Characteristics
The 1794-TB3G operates as a passive terminal base interface within the Allen Bradley Flex I/O platform. The unit provides electrical termination points for Flex I/O modules through 36 I/O terminals, two common terminals, and two voltage terminals. The terminal base supports DIN rail installation and screw-clamp field wiring connection.
The Flex I/O architecture uses modular I/O density scaling, allowing terminal bases to be installed as part of distributed control assemblies. The terminal base provides the physical connection layer between field wiring and the associated I/O module electronics.
Frequently Asked Questions (FAQ)
Q: What type of mounting interface is used by the 1794-TB3G?
A: The 1794-TB3G uses DIN rail mounting for installation within Flex I/O distributed I/O assemblies.
Q: Does the 1794-TB3G provide direct I/O signal processing?
A: No. The terminal base provides field wiring termination and module connection functions. Signal processing is performed by the installed Flex I/O module.
Q: What field wiring connection method is supported?
A: The unit uses screw-clamp terminals with supported conductor sizes from 24 to 16 AWG.
Field Installation Guidelines
Install the terminal base on a properly secured DIN rail and verify mechanical engagement before connecting field conductors. Maintain separation between signal wiring and high-voltage power conductors to reduce electrical interference.
Use the specified conductor size range and apply terminal screw tightening according to the documented torque range. Ensure grounding requirements are followed when installing grounded terminal configurations.
For shielded signal cables, connect cable shields according to the control system grounding practice and avoid multiple unintended ground paths. Verify terminal identification before energizing the connected Flex I/O assembly.
