Allen-Bradley 1769-PB4 Push Button Interface Module provides four push-button input channels for Compact I/O, designed for use with CompactLogix controllers and the 1769 backplane. This module accepts four independent push-button signals to capture operator actions in automation sequences and process control. It requires a compatible 1769 power supply to power the I/O rack, such as a 1769-PA2 or 1769-PA4 (or 1769-PB2/PB4) power module, depending on the system configuration. Common uses include manual start/stop control, cycle initiation, remote reset, and other operator-input tasks in manufacturing automation.
