Allen-Bradley 5094-RTB3I Removable Terminal Block

Product Overview

The Allen-Bradley 5094-RTB3I is an isolated screw-type Removable Terminal Block (RTB) designed for the FLEX 5000 I/O system. It is used as the field wiring interface for FLEX 5000 I/O modules, providing convenient connection and replacement of field-side wiring without removing the complete I/O module.

The 5094-RTB3I features isolated I/O channels, helping protect field devices and control systems from electrical interference and unwanted voltage interaction.
