The Allen-Bradley 1756-OA8D is a ControlLogix 120V AC diagnostic output module for the 1756 chassis. It has eight diagnostic outputs with electronic fusing in two groups of four for 120V AC loads, with an operating range of 74…132V AC at 47…63 Hz, up to 0.5 A per point and 4 A per module at 60 °C (140 °F). It draws 175 mA at 5.1V DC and 250 mA at 24V DC from the backplane. Field wiring goes through a 1756-TBNH or 1756-TBSH removable terminal block, which is ordered separately. ControlLogix I/O modules can sit in any slot of a local ControlLogix chassis or in a remote chassis linked over EtherNet/IP or ControlNet, and their input data and output status can be shared by more than one controller.
