Technical Specifications for 1756-TBCH

About  1756-TBCH

The Allen-Bradley 1756-TBCH is a Removable Terminal Block (RTB) for 1756 I/O modules. It is an I/O module accessory and must be ordered separately. The 1756-TBCH provides flexibility in interconnecting 1756 I/O modules and industrial plant wiring. It plugs into the front of an I/O module.

The 1756-TBCH removable terminal block is a 36-pin cage-clamp with standard housing (wiring arm depth of 2.5 mm. sq.). When terminating signal to the RTB, the required Torque is 0.5 Nm screw torque. It is recommended to use a screwdriver with width of 3.2 mm (1/8 in.) Screwdriver width. It has dimensions of 5.51 x 4.41 x 5.71 in. and weighs 0.3 pounds. For wiring, use solid or stranded copper wire rated at 90 deg. Celsius (194 °. Fahrenheit) or greater with a gauge 1.2 mm (3/64 in.) maximum insulation must be used. In case of a single wire connection, the wire size must be 0.33 - 2.1 mm sq. (22 - 14 AWG), and for a double wire connection, the wire size must be 0.33 - 1.3 mm sq. (22 - 16 AWG). On any single terminal, do not wire more than two conductors.

Each ControlLogix I/O module can mount in any ControlLogix chassis and they all require a removable terminal block (RTB) to connect all the field-side wiring. Each I/O module has many applications ranging from high-speed digital processing to process control. In a ControlLogix architecture, input and output status are shared between multiple controllers in the same or different chassis using producer-consumer technology. The 1756-TBCH RTB is intended for use in a clean and dry industrial environment with a 0-60 deg. Celsius operating temperature and a 30g operating Shock.

The 1756-TBCH is a 36-Pin cage clamp Removable Terminal Block (RTB) that is used to provide modular and flexible wiring terminal for Input and Output devices. This RTB is a module component that installs in the front of a ControlLogix I/O module, hidden by the module door cover.
