The Allen-Bradley 1756-OX8I is a robust relay output module designed for the ControlLogix platform, featuring eight normally open and eight normally closed contacts, each individually isolated to accommodate a versatile range of AC voltages from 10 to 240 VAC and DC voltages from 5 to 125 VDC. This flexibility allows the module to efficiently control a variety of output devices such as contactors, motor starters, and variable frequency drives, catering to different voltage requirements. Installation and maintenance are streamlined with the use of compatible removable terminal blocks, 1756-TBCH and 1756-TBS6H, which facilitate modularized output termination, reduce re-wiring needs, and ensure a seamless replacement process.
