1794-TBN Heavy Duty NEMA Barrier Strip Terminal Base for High Voltage Industrial FLEX I/O Systems
Product Overview
The 1794-TBN is a FLEX I/O terminal base with a NEMA barrier strip design. The screw terminals keep field wiring in place, which is useful for applications where vibration is a concern. With support up to 250V AC/DC, it is commonly used for higher voltage wiring in power plants and heavy industrial systems.
NEMA Barrier Strip: Screw terminals provide a solid connection for industrial field wiring, especially in vibration-prone environments.
250V AC/DC Rating: Suitable for higher voltage control circuits without adding extra relay components in many installations.
Engineer's Note: The 1794-TBN is a good fit when a strong screw connection is needed. It does not include built-in fuses, so projects requiring individual channel protection should consider the 1794-TBNF instead.
Project Case: Globally standardized to connect high-voltage field devices under continuous vibration.

Frequently Asked Questions
Q1: Where do you usually see the Allen-Bradley 1794-TBN used?
A1: The 1794-TBN terminal base is normally installed with an Allen-Bradley FLEX I/O system. Field wires are landed on the terminal base first, then connected with the I/O module inside the control cabinet. It is a common choice for distributed I/O wiring in industrial equipment.
Q2: What is different about the 1794-TBN terminal design?
A2: The 1794-TBN uses a screw terminal barrier strip style connection. Compared with some spring clamp bases, this design gives technicians a more familiar way to check and tighten field wiring during maintenance.
Q3: Can the 1794-TBN handle higher voltage field wiring?
A3: Yes, the terminal base supports up to 250V AC/DC isolation. It is often used where PLC I/O wiring needs to connect with higher voltage control circuits.
Q4: Does the 1794-TBN come with fuse protection?
A4: No, the standard 1794-TBN is a non-fused terminal base. For applications needing fuse protection, users usually look at the 1794-TBNF version.
Q5: What industries use the 1794-TBN?
A5: The Allen-Bradley 1794-TBN is commonly found in power plants, steel production lines, petrochemical automation, and other heavy industrial control systems.
