Designed with a nominal 61.5 Ohm sense resistor and total input resistance of 280 Ohm, the module transparently decouples superimposed HART digital FSK signals while delivering 15-bit conversion resolution at a 100 ms per channel update rate.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary functional difference between standard 4-20 mA inputs and the FBM214B RH927AH?\u003c\/p\u003e\n\u003cp\u003eA: The FBM214B simultaneously processes standard 4-20 mA analog primary variables while maintaining continuous FSK digital communication with HART-compliant field transmitters for secondary variable monitoring and device diagnostics.\u003c\/p\u003e\n\u003cp\u003eQ: Can the FBM214B input channels be hot-swapped while the DCS baseplate is powered?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
