The Allen-Bradley 1756-OB8I is a ControlLogix DC isolated output module designed for precision and reliability, featuring eight individually isolated outputs suitable for pilot duty applications. With an operating voltage range from 10 to 30 volts DC, the module delivers a current draw of 165 mA at 5.1 volts and 2 mA at 24 volts, ensuring efficient performance. Notably, it supports various communication formats, including Rack Optimization and Scheduled Output Data, and allows for tailored responses in Fault or Program mode with default settings at 'Off.' Installation requires a 36-pin removable terminal block housing, either the 1756-TBCH or 1756-TBS6H, in a properly grounded and installed chassis, while a fused IFM is advised for output protection.
