Selection Suggestions and Precautions
Selection Suggestions
- Choose GE IC697ALG320 for Series 90 – 70 PLC systems needing 4 configurable analog outputs with high resolution and isolation.
- Prefer it for process control apps (valve/motor control) requiring software – configurable signal types and fast conversion rates.
Precautions
- Avoid exceeding ±12V or 25mA on outputs to prevent damage to GE IC697ALG320’s DAC circuitry.
- Use shielded twisted – pair cables for output wiring to minimize noise interference with GE IC697ALG320.
- Verify EEPROM calibration data integrity during system startup to ensure GE IC697ALG320 accuracy.
- Ensure proper baseplate grounding to maximize GE IC697ALG320’s backplane isolation effectiveness.
- Do not hot – swap GE IC697ALG320; power down the 90 – 70 chassis before module installation/removal.
