GE IC697ALG320 – Series 90‑70 4‑Channel High‑Resolution Analog Output Module

In stock

Product Introduction:

The IC697ALG320 is a high‑precision analog output module for the Emerson (formerly GE Fanuc) Series 90‑70 PLC platform, providing four independently configurable analog output channels. It converts digital signals from the PLC into precision current (0–20mA/4–20mA) or voltage (-10V to +10V) signals to control field devices such as modulating valves, VFDs, and proportional controllers. Engineered for process‑critical applications, it offers 16‑bit resolution, factory calibration, and advanced diagnostics for accurate and reliable control in harsh industrial environments.

Key Features

4 Independent Configurable Channels: Each channel independently set for current (4–20mA) or voltage (±10V) outputs via software, eliminating hardware changes.
16‑Bit High Resolution: Delivers precise analog‑to‑digital conversion for accurate control of small signal changes in closed‑loop systems.
Factory Calibrated: Pre‑calibrated at the factory with calibration data stored in non‑volatile EEPROM, ensuring long‑term accuracy without user calibration.
Fast Update Rate: 2ms per channel ensures responsive control for dynamic processes like flow regulation and pressure modulation.
Diagnostic LEDs: Group‑level fault LEDs (red = channel error) and overrange/underrange flagging enable quick troubleshooting.
Hot‑Swappable: Allows replacement during system operation to minimize downtime in critical applications (system‑dependent).
Rugged Industrial Design: Withstands vibration, shock, and wide temperature ranges for reliable operation in chemical, petrochemical, and water treatment plants.
