GE Fanuc IC697ALG320 Analog Output Module

Overview

The IC697ALG320 is a high-performance 4-channel analog output module designed for use with GE Fanuc's Series 90-70 Programmable Logic Controllers (PLCs). This module allows users to generate both voltage and current output signals. Each channel is independently configurable, offering flexibility in diverse industrial applications. The module features a high-resolution 16-bit DAC with 14-bit monotonicity for precise analog signal conversion.
