While the module is non-isolated, careful attention must be paid to channel-to-channel and system-to-field grounding to prevent common-mode noise. Cold junction compensation is not implemented internally; external signal conditioning is recommended if precise low-level DC measurement is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequentlyAskedQuestions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eQ: Does the AMM52 support hot-swapping?\u003cbr\u003eA: No. The module must be powered down before removal or replacement to prevent backplane bus damage.\u003c\/p\u003e\n\u003cp\u003eQ: What is the expected switching delay between input channels?\u003cbr\u003eA: The scan period is 1 second per standard RIO multiplexer sequencing; channel-to-channel switching occurs within this cycle.\u003c\/p\u003e\n\u003cp\u003eQ: Can the module operate with varying backplane voltages?\u003cbr\u003eA: The module is rated for 5 VDC backplane supply.
