Description
Product Description
The GE IC697MDL671 is a 24VDC discrete interrupt input module belonging to the GE Series 90-70 PLC system, which offers 16 input points divided into four isolated groups of four points each. Among these, the first 14 points (A1 – D2) serve as interrupt inputs, and the last two (D3 – D4) are configuration inputs, with all 14 interrupt points capable of running at the maximum I/O interrupt rate. The GE IC697MDL671 is designed with positive/negative logic compatibility, selectable input filters (1ms or 10ms), and LED indicators for each point’s on – off status, which enables it to be widely used in industrial automation scenarios that demand rapid response and precise control. As a key component of the Series 90-70, the GE IC697MDL671 integrates seamlessly with GE’s programming software and communication protocols, and its mechanical keying feature prevents incorrect installation, significantly enhancing on – site maintenance efficiency.

Selection Suggestions and Precautions
- Selection Suggestions
- Prioritize the GE IC697MDL671 for applications requiring ≥10 high – speed interrupt inputs and isolated groupings to minimize cross – talk.
- Match the module with 24VDC sensors (proximity switches, limit switches) and confirm compatibility with positive/negative logic requirements.
- Ensure it integrates with GE Series 90-70 CPUs and use GE’s programming software for configuration.
- Precautions
- Do not exceed the 13.5-30VDC operating voltage range to avoid damaging the GE IC697MDL671.
- Set the input filter (1ms/10ms) based on field noise levels; shorter filters suit fast signals, longer ones reduce false triggers.
- Use only GE – approved mechanical keys to prevent incorrect module insertion and ensure system integrity.
- Configure D3/D4 as per the application; improper setup may disable interrupt functions.
- Operate the GE IC697MDL671 within -25°C to +60°C and ≤95% humidity (non – condensing) for long – term reliability.
