The IC670ALG240-CB (Model: IC670ALG240-CB) is a high-density, high-resolution analog input module part of the GE Fanuc Field Control I/O series. This module is specifically engineered for precision current-source data acquisition, providing eight (8) single-ended channels. The IC670ALG240-CB (Part Number: IC670ALG240) stands out in the Field Control family by offering 16-bit ADC resolution, allowing for much finer granularity in process variable monitoring compared to standard 12-bit modules.
Designed for robust performance in distributed control architectures, the IC670ALG240-CB features an integrated 2nd order RC hardware filter and a high common-mode rejection ratio (CMRR) of 86 dB. These features ensure signal integrity when interfacing with field transmitters over long cable runs susceptible to industrial electromagnetic interference. The module is fully compatible with ANSI Type 2 and Type 3 two-wire transmitter configurations and provides a critical safety barrier with 1500 VAC galvanic isolation.
The IC670ALG240-CB provides professional-grade signal conditioning for critical industrial loops.
