This analog output module converts digital data from the PLC CPU into precise voltage or current signals. It drives field actuators, valves, and variable frequency drives in industrial control loops. The module integrates seamlessly into GE Series 90-70 PLC systems for reliable process control.
Channel Configuration and Signal Output
The GE IC697ALG320 provides four individually configurable output channels for maximum application flexibility. Each channel can operate in voltage mode with a -10V to +10VDC range or in current mode with 0-22.5mA range. The default current configuration is 4-20mA for standard industrial compatibility. A 16-bit digital-to-analog converter delivers high output resolution with 14-bit monotonicity. No jumpers or DIP switches are required for configuration as all settings are software-driven.

Factory Calibration and Diagnostic Features
The module arrives fully calibrated from the factory and stores calibration data in nonvolatile EEPROM memory. This design eliminates the need for frequent recalibration and maintains long-term accuracy. The module provides comprehensive diagnostics including overrange, underrange, open-wire detection, and module health monitoring. Short-circuit protection safeguards the outputs with automatic recovery after the fault clears. Front-panel LEDs indicate BOARD OK status and channel activity for quick troubleshooting.
System Integration and Application Use
This module occupies a single slot in a Series 90-70 baseplate and communicates via the PLC backplane. Each output channel uses one word (16 bits) of %AQ memory for data reference. Users can scale individual outputs through programming software to suit specific application requirements. The module finds widespread use in process control, power generation, chemical processing, water treatment, and manufacturing facilities. Its robust design ensures reliable operation in demanding industrial environments with minimal maintenance overhead.
