PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1756-TBCH/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1756-TBCH is a ControlLogix 36 Pin Cage-Clamp Terminal Block. It provides screw-clamp cage-clamp field wiring connections for compatible ControlLogix systems. The assembly provides 36 termination pins for signal and power circuits. Technicians can remove the block from the module without disconnecting field wiring conductors. This removable terminal block design helps reduce wiring errors during maintenance procedures.
The unit supports single-wire terminations from 0.33 to 2.1 square millimeters. That range corresponds to 22 through 14 AWG wire sizes. For double-wire terminations, the block accepts 0.33 to 1.3 square millimeters or 22 to 16 AWG. Fasten all terminal screws to a torque specification of 0.5 Newton meters. The block operates in ambient temperatures between 0 and 60 degrees Celsius.
