Allen-Bradley ControlLogix 20 Pin Screw Terminal Block 1756-TBNH
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 I/O modules. The RTB plugs into the front of the I/O module. The type of module determines the RTB you need. You can choose screw-clamp or spring-clamp RTBs.
RTBs are not shipped with I/O modules. You must order them separately. The standard housing on the front of the wiring arm is not necessarily deep enough for 2.5 mm2 (14 AWG) wiring. If you plan to use 2.5 mm2 (14 AWG) wiring, also order the extended housing.
