Product Description:
The IC670ALG230 is an analog input module from GE Fanuc. It specifically belongs to the Field I/O control product family of expansion modules that operate with a compatible Bus Interface Unit (BIU). This module primarily features Eight (8) Analog input channels that accepts 0-20 mA and 4-20 mA analog input signals. This module is mainly used for interfacing of field signal transmitters of many types, outputs of panel meters, data loggers, signal splitters, Variable Frequency Drives (VFD) and similar devices.
The IC670ALG230 has analog resolution of 5.0 µA while the digital resolution is 12 bits, typical. It accepts a minimum input current of 0.1 mA and maximum of 20 mA. It is built with internal protection features such as open wire detection and over-range fault detection.
The IC670ALG230 has built-in analog to digital converter (ADC) circuit which converts the received analog signal to digital format for processing of the host CPU. The ADC circuit has a conversion time of 60 µs per channel at 1 MHz module clock. It also has a 1st order RC input filter with typical transition capacity of 160 Hz.
