This module provides high-precision signal conversion, transforming 4-20mA current loop inputs into 12-bit digital values for processing by the Bus Interface Unit (BIU). Engineered for industrial environments, it features robust electrical isolation to protect sensitive backplane components from field-side electrical noise and surges.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8-channel 4-20mA analog input capacity.\u003c\/li\u003e\n\u003cli\u003e12-bit resolution for precise signal monitoring.\u003c\/li\u003e\n\u003cli\u003eHigh isolation ratings: 400VDC channel-to-channel and 1,000VDC channel-to-bus.\u003c\/li\u003e\n\u003cli\u003eCompatible with standard Field Control I\/O bases for flexible termination.\u003c\/li\u003e\n\u003cli\u003eSupports hot-swapping on Revision C and higher hardware.\u003c\/li\u003e\n\u003cli\u003eInput impedance of 100 ohms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is intended for use in distributed I\/O systems where analog process variables (such as pressure, flow, or temperature transmitters) must be interfaced with a PLC or control system.
