The module's compact 2-point configuration supports I\/O density scaling without requiring dedicated field wiring changes to adjacent modules. Firmware compatibility should always be verified against the installed POINT I\/O adapter and controller revision before commissioning or replacement activities. The module draws 75 mA from the POINTBus while executing output commands received through the system's deterministic control network infrastructure.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are the two output channels galvanically isolated from each other?\u003c\/strong\u003e\u003cbr\u003eA: No. The two sourcing output channels share a common internal design and are not isolated from each other.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What protection method is provided for the outputs?\u003c\/strong\u003e\u003cbr\u003eA: The module incorporates electronic output protection intended to protect the output circuitry during fault conditions associated with the connected load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the module switch loads directly at 24 VDC?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
