Allen-Bradley 1769-RTB40DIO is a 40-terminal remote terminal block designed as the removable terminal kit for the embedded digital I/O on CompactLogix 5370 L2 controllers. The unit provides four 10-pin connectors to connect field wiring to the controller’s embedded digital I/O module, enabling a compact, swappable interface for DI/O. As a replacement terminal block, it is used with CompactLogix 5370 L2 systems to wire the embedded I/O without disturbing the main controller. This RTB consolidates the wiring interface for the 1769-L24ER family of controllers, simplifying maintenance and replacement of I/O wiring connections.
