The Allen-Bradley 1756-OC8 is a ControlLogix DC output module offering reliable performance with its 8-point capacity, grouped into two sets of four. Engineered for a 48V DC source, its operating voltage ranges between 30 and 60V DC, supporting a pilot duty of 2A and a current draw of 165 mA at 5.1V, with a backplane power requirement of 0.89 W. Its design necessitates the use of a fused interface module for output protection, accommodating a quick-acting 4A fuse. Installation requires the pre-setup of the chassis and power supply, along with the use of compatible 20-pin removable terminal blocks such as the 1756-TBNH or 1756-TBSH. Key features include communication formats like rack optimization and the ability to select fault or program modes per point, with options including On, Off, and Hold Last State.
