A-B Rockwell 1756-TBNH Removable Terminal Block or RTB Module

The 1756-TBNH module is a removable terminal block or RTB module.

It is manufactured by Allen-Bradley/Rockwell Automation in the ControlLogix family.

The wires connected to the 1756-TBNH detachable terminal block should all be the same size.

and they should all be solid wire or all stranded wire, as the block does not support a mix of solid and stranded wire.

This detachable terminal block is a NEMA clip type detachable terminal block.

The 1756-TBNH detachable terminal block can be used with up to 20 wires at a time.

The Allen-Bradley 1756-TBNH is a removable terminal block (RTB) for the 1756 I/O module.

It is an I/O module accessory and must be ordered separately.

The 1756-TBNH provides flexibility in interconnecting 1756 I/O modules and industrial plant wiring. It plugs into the front of the I/O module.

The 1756-TBNH removable terminal block is a 20-position NEMA screw clamp.

It has a screw torque of 1.36 Nm and a screwdriver width of 8 mm (5/16 in.)**.

It measures 5.51 x 4.41 x 5.71 inches. It weighs 0.3 lbs.

Wiring must be done with 0.33 - 2.1 mm-^2 (22 - 14 AWG) solid or stranded copper wire.

rated for 90 °C (194 °F) or higher,** with 1.2 mm (3/64 in.) of insulation.

Do not connect more than two conductors to any single terminal.

Each ControlLogix I/O module is mounted on any ControlLogix chassis and requires a removable connector.

Each ControlLogix I/O module is mounted on any ControlLogix chassis and requires a removable terminal block (RTB) for all field-side wiring.

Each I/O module has many applications, 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 using producer-consumer technology.

The 1756-TBNH RTB is intended for use in clean, dry industrial environments with operating temperatures of 0-60 °C and 30 g of operating shock.
