Cold junction compensation (CJC) is applied for temperature-sensitive signal stability. These characteristics ensure integrity and consistency of analog and digital data exchange between field instruments and central I\/O modules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the RB301 support hot-swap of RIObus devices?\u003cbr\u003eA: The RB301 does not natively support hot-swap; all device additions or replacements must be performed with system power disabled to maintain bus integrity.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum number of devices per RIObus segment?\u003cbr\u003eA: Up to 31 devices can be connected per RIObus segment.
