FAQ

• Points? 32 source outputs.
• Current per point? 500 mA.
• Hot-swappable? No (use R/C versions if required).

Installation Guide

1. Install the module in the I/O card file.
2. Attach the matching terminal block (621-9976/9977).
3. Wire field loads observing polarity and group limits.
4. Apply field power with fast rise time (<0.5 ms/V).
5. Verify outputs and clear any over-current faults if present.

Selection Tips

• Ideal for high-density 24 VDC discrete output needs.
• Observe group current limits carefully.
• Consider the R/C hot-swap version for online maintenance.
