<strong>ControlLogix</strong> I/O Modules 6-7<strong>Us<strong>in</strong>g</strong> Digital OutputModules<strong>ControlLogix</strong> digital output modules are divided <strong>in</strong>to two categories:• Diagnostic output modules• Standard output modulesThese modules share many of the same <strong>in</strong>herent architecturalcharacteristics. However, the diagnostic output modules <strong>in</strong>corporatefeatures that allow diagnos<strong>in</strong>g of field-side failures. These features<strong>in</strong>clude report<strong>in</strong>g No-Load conditions and po<strong>in</strong>t-level fuse-blown. Inaddition, the diagnostic modules can validate the state of the outputwith the Output Verify feature and the Output Pulse test.Table 6.3 lists the digital output modules that are suitable for use <strong>in</strong><strong>SIL2</strong> applications.Table 6.3 <strong>ControlLogix</strong> Digital Output Modules Suitable for <strong>SIL2</strong> ApplicationsModule Type: Catalog Number: Description:Diagnostic Output Modules <strong>1756</strong>-OB16D DC Diagnostic OutputModule<strong>1756</strong>-OA8DAC Diagnostic OutputModuleStandard Output Modules <strong>1756</strong>-OB16I DC Isolated Output Module<strong>1756</strong>-OA16IAC Isolated Output Module<strong>1756</strong>-OB8EIDC Isolated Output Module<strong>1756</strong>-OX8IIsolated Relay OutputModulePublication <strong>1756</strong>-<strong>RM001B</strong>-<strong>EN</strong>-P - October 2003
