The Allen-Bradley 1756-TBNH is a removable terminal block (RTB) module designed for use with ControlLogix I/O modules. It provides a convenient interface for field wiring connections and supports up to twenty (20) conductors. The 1756-TBNH features a NEMA clamp-style connection, ensuring secure and reliable wire termination. All connected wires should be of the same size and type—either all solid or all stranded—as mixing solid and stranded conductors is not supported. This removable terminal block simplifies installation and maintenance, providing dependable connectivity for ControlLogix applications.
