      Features:

      • ControlLogix removable terminal block
      • Removable terminal block or RTB module
      • ControlLogix series by Allen-Bradley/Rockwell Automation
      All wires connected to the 1756-TBNH detachable terminal block must be of the same size and must be either all single-strand or all multi-strand, as this terminal block does not support mixed single-strand and multi-strand wiring. This detachable terminal block is a NEMA clip-on terminal block. The 1756-TBNH detachable terminal block can connect up to 20 wires at a time.

      The Allen-Bradley 1756-TBNH is a detachable terminal block (RTB) for the 1756 I/O module. It is an accessory for the I/O module and must be ordered separately. The 1756-TBNH provides flexible wiring for connecting the 1756 I/O module and industrial equipment. It inserts into the front of the I/O module. The 1756-TBNH detachable terminal block is a 20-position NEMA screw clip-on terminal block. Its screw torque is 1.36 Nm, and the maximum screwdriver width is 8 mm (5/16 inch). It measures 5.51 x 4.41 x 5.71 inches and weighs 0.3 lbs.

      The 1756-TBNH Allen Bradley ControlLogix removable terminal block may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      Allen Bradley 1756-TBNH ControlLogix removable terminal block Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      Do not connect more than two wires to any single terminal. Each ControlLogix I/O module can be installed in any ControlLogix chassis and requires a removable terminal block (RTB) for all field wiring. Each I/O module has a variety of applications, covering everything from high-speed digital processing to process control. In the ControlLogix architecture, input and output states are shared between multiple controllers in the same or different chassis via producer-consumer technology.

      • What functional interconnection role does 1756-TBNH perform within a ControlLogix I/O module architecture?
        The 1756-TBNH serves as a 20-position removable terminal block (RTB) engineered to provide high-integrity field wiring termination for compatible ControlLogix digital and analog I/O modules, ensuring reliable signal continuity between external devices and the backplane-mounted module electronics.
      • The 1756-TBNH serves as a 20-position removable terminal block (RTB) engineered to provide high-integrity field wiring termination for compatible ControlLogix digital and analog I/O modules, ensuring reliable signal continuity between external devices and the backplane-mounted module electronics.
        The 1756-TBNH incorporates a screw-clamp termination mechanism with secure conductor retention, vibration-resistant clamping force, and optimized contact metallurgy to maintain low contact resistance and stable signal transmission in industrial environments.
      • Why is the 20-terminal configuration of 1756-TBNH significant for channel density optimization in ControlLogix systems?
        The 1756-TBNH provides a high-density termination format that aligns precisely with the channel mapping of specific I/O modules, enabling efficient panel space utilization while maintaining structured field wiring organization.
      • In what way does the removable nature of 1756-TBNH facilitate maintenance and module replacement procedures?
        The 1756-TBNH supports rapid I/O module exchange by allowing technicians to detach the terminal block without disturbing field wiring, thereby minimizing downtime and reducing the probability of wiring errors during service operations.
      • How does 1756-TBNH contribute to electromagnetic compatibility within high-noise industrial installations?
        The 1756-TBNH supports structured grounding practices and controlled conductor separation to mitigate electromagnetic interference, ensuring signal integrity in environments with high-frequency drives or heavy electrical loads.
