As part of the IC697 Series, the IC697ALG320 integrates seamlessly with other 90-70 Series components, such as CPU modules and digital I/O modules, enabling robust and scalable control solutions for power generation, oil & gas, and manufacturing sectors.
Featuring a rugged industrial design, the GE IC697ALG320 supports 16 isolated analog input channels, each configurable to accept multiple signal types including 4–20 mA current loops, 0–10 V DC voltages, and resistance temperature detector (RTD) signals. Its 16-bit resolution and ±0.1% full-scale accuracy ensure precise measurement of process variables like temperature, pressure, and flow rate. The module’s advanced signal conditioning includes anti-aliasing filters and galvanic isolation (250 V RMS per channel), minimizing noise interference and protecting the PLC system from ground loops. With a wide operating temperature range (-40°C to +70°C) and compliance with IEC 61131-2 standards, the IC697ALG320 is ideal for harsh environments, such as offshore platforms, refineries, and heavy manufacturing facilities.
In automation ecosystems, the IC697ALG320 acts as the interface between analog field devices and the PLC control layer, enabling real-time data transmission for process optimization and safety monitoring. Its hot-swappable design allows module replacement without system shutdown, reducing downtime during maintenance. By combining high-density input channels with advanced diagnostic capabilities, this module enhances system efficiency and reduces total cost of ownership, making it a cornerstone of reliable industrial control strategies.
