The IC697ALG230 is a base converter module designed for use with the Series 90-70 PLC system. Manufactured originally by GE Fanuc (now under Emerson Automation), it serves as a critical component in high-level analog input systems. This module offers eight differential inputs, each configurable for voltage or current signals, and supports both 4-20 mA current and -10V to +10V voltage inputs. With a high resolution of 16-bits per channel and fast update rates, it ensures precise and timely signal conversion.
