Attempting to switch DC loads will result in the output failing to turn off (latched state) or may damage the internal semiconductors. Use a DC output module like the 1794-OB16 for DC applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the outputs isolated from each other?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The 1794-OA16 features non-isolated outputs that share a common AC return path within the module.
