The Allen-Bradley 1756-TBCH is a ControlLogix Detachable Terminal (RTB) assembly. This component is used as a modular terminal for the 1756 I/O module. The assembly is a 36-pin cage clamp removable terminal with standard housing.

The Allen-Bradley 1756-TBCH is a detachable terminal (RTB) for the 1756 I/O module. It is an I/O module attachment and must be ordered separately. The 1756-TBCH provides flexibility for interconnecting 1756 I/O modules and industrial plant cabling. It plugs into the front of the I/O module.

The 1756-TBCH detachable terminal is a 36-pin cage fixture with a standard housing (terminal arm depth of 2.5 mm. sq.). When the signal is terminated to the RTB, the required torque is 0.5 Nm helix torque. A screwdriver with a width of 3.2 mm (1/8 inch) is recommended. It measures 5.51 x 4.41 x 5.71 inches. It weighs 0.3 pounds. When connecting cables, use solid or stranded copper cables with a temperature rating of 90 degrees. 194° C. Fahrenheit) or higher, must use a maximum insulation layer of 1.2 mm (3/64 inch) specifications. For a single wire connection, the wire size must be 0.33-2.1 square millimeters (22-14 AWG), and for a two-wire connection, the wire size must be 0.33-1.3 square millimeters (22-16 AWG). Do not connect more than two conductors to any single terminal.

A terminal is a connector used to connect electrical or electronic devices, which allows the establishment of electrical connections between different circuits or devices. Terminals are usually made of metal and have multiple connection points, each of which can be connected to one or more wires.

A-b 1756-TBCH A terminals are commonly used in circuit boards, control cabinets, distribution boxes and other devices to connect various electrical components, such as sensors, motors, switches, light bulbs and so on. They provide a convenient and reliable connection that simplifies the assembly and maintenance of equipment.

A-b 1756-TBCH A There are many types and specifications of terminal blocks. Common types include:

1. Pin terminal: This terminal usually has one or more rows of metal pins for insertion into the socket on the circuit board.

2. Stud terminal: A-B 1756-TBCH A This terminal usually has A stud or nut for attaching the wire to the terminal.

3. Crimp type terminal: A-B 1756-TBCH A This terminal usually uses A crimp tool to crimp the wire to the terminal, without the use of studs or nuts.

4. Spring type terminal: This terminal usually has a spring piece, which is used to fix the wire on the terminal, and provides a certain elasticity and vibration resistance.

When selecting terminals, you need to consider parameters such as the number of wires connected, current and voltage to ensure the reliability and safety of the connection. At the same time, it is also necessary to consider the installation mode, size and protection level of the terminal to adapt to different application environments.
