The Allen-Bradley 1771-OW16 is a versatile electromechanical relay contact output module from the 1771 series, designed to accommodate both AC and DC voltage ranges of 24-250VAC and 24-150VDC. It features a total of 16 outputs, with eight channels as Normally Open and eight as selectable Normally Open or Normally Closed, providing operational flexibility. This module is engineered for optimal isolation through two groups of eight outputs, ensuring individual channel failures do not impact others. It relies on a backplane power supplied by the 1771 I/O chassis and requires the 1771-WN wiring arm for secure electrical connections, enabling relay output removal without disrupting the wiring. Effective in reducing electromagnetic interference, it requires an RC network filter and is designed for seamless integration with the 1771 I/O system's slots, providing robust performance for industrial power applications.
