Onboard 16-bit A\/D converters sample incoming field loops at up to 1 kHz per channel, processing high-bandwidth transducer signals without overloading primary control bus bandwidth. Channel-to-channel galvanic isolation blocks high common-mode voltages and electrical noise, preserving signal conversion accuracy within +\/-0.1% of full scale across real-time continuous process control applications.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the IMFAI02 module handle ground potential differences between remote sensors and the backplane?\u003c\/p\u003e\n\u003cp\u003eA: Integrated galvanic isolation electrically separates each of the 8 input channels from internal logic circuitry and system ground buses, preventing ground loops and protecting backplane components from field surge voltages.\u003c\/p\u003e\n\u003cp\u003eQ: Is external field power required to drive 4-20 mA current loops connected to the IMFAI02 module?\u003c\/p\u003e\n\u003cp\u003eA: The module relies on +5 VDC from the backplane for internal processing circuits.
