Advantages and Features
- Flexible Channel Configuration
Each channel of the GE IC697ALG320 is independently set for voltage or current outputs, adapting to diverse actuator types (valves, drives, transmitters) without hardware modifications.
- High Precision and Stability
16-bit DAC resolution and factory EEPROM calibration ensure long-term accuracy, while output-backplane isolation prevents ground loops and transient damage.
- Software-Centric Setup
No jumpers/DIP switches—configurations are done via MS-DOS/Windows software, reducing setup time and human error during commissioning.
- Compact and Reliable Design
Single-slot form factor saves space; continuous short-circuit protection and rugged construction enhance reliability in industrial environments.
Application Cases in Application Fields
- Chemical Process Control
A European chemical plant integrated the GE IC697ALG320 into its Series 90-70 PLC to control reactor temperature and pressure valves. Individual channel configuration allowed mixing voltage-controlled heaters and current-controlled pressure regulators, cutting calibration time by 50% and improving process stability by 35%.
- Water/Wastewater Treatment
A municipal treatment facility used the GE IC697ALG320 to drive 4-20mA flow control valves and -10V to +10V variable frequency drives (VFDs). Isolation protected the PLC from sensor transients, reducing unplanned downtime by 28%.
- Automotive Manufacturing
An automotive assembly plant deployed the GE IC697ALG320 to control robotic arm positioners and conveyor speed drives. Fast conversion rates (2.0 ms) ensured real-time response, improving production line throughput by 18%.

Selection Suggestions and Precautions
Selection Suggestions
- GE Series 90-70 Users
Choose the GE IC697ALG320 for native compatibility with Series 90-70 baseplates, ensuring plug-and-play integration and reliable communication with GE CPUs.
- Mixed Signal Requirements
Ideal for applications needing both voltage and current outputs on the same module, such as process control with valves, VFDs, and transmitters.
- Space-Constrained Cabinets
Its single-slot design suits 5-slot or 10-slot baseplates, optimizing space in compact control environments.
Precautions
- Power Supply Compliance
Ensure backplane power (5VDC, max 1.66A) and user power (150mA for current outputs) meet specifications to avoid module damage.
- Configuration Best Practices
Use GE’s programming software for channel setup—avoid hardware workarounds (no jumpers/DIP switches).
- Isolation and Grounding
Connect outputs to floating or same-potential loads; keep compliance voltage differences ≤0.5VDC between outputs to prevent ground loops.
- Maintenance Checks
Periodically verify calibration via EEPROM data; inspect for short circuits and clean module surfaces to maintain heat dissipation efficiency.
