Compatible Terminal Base Units
1794-TBNK, 1794-TBKD, 1794-TB3K, 1794-TBNFK, 1794-TB3SK, 1794-TBNF, 1794-TB3, 1794-TB2, 1794-TB3S, and 1794-TBN. Auxiliary terminal strips are required when using the 1794-TBN base unit.
Installation Notes
Install directly on compatible Flex I/O terminal base units. Use auxiliary terminal strips when mounting on the 1794-TBN base. Observe current derating based on ambient temperature: 500 mA per output at 55°C, 750 mA at 35°C. Verify off-state leakage does not affect connected loads. Ensure proper grounding per Allen-Bradley wiring guidelines. Suitable for non-hazardous and Class 1 Division 2 environments.
Engineering Advantages
Integrated diagnostics identify faults in field devices, wiring, and power supply, reducing commissioning and troubleshooting time. 8 outputs in a single Flex I/O module maximize channel density. High 4.0 A module rating handles demanding AC loads directly. Surge current capability of 7 A supports inductive load switching. Wide 85-132V AC range accommodates supply variations. Modular Flex I/O design enables flexible system expansion.
