Digitally Isolated 2-Channel, Wide AC/DC Binary Input Module Reference Design
Description
This reference design enables translation of wide range AC and DC voltage inputs up to 276V into binary logic level voltages that a typical electronic circuit can handle. This solution is flexible, not only handling input voltages from 15V to 276V but also allowing programmable switching thresholds to set binary levels. In addition, this solution enables < ± 3.0% (± 1V measured value step size) error in voltage detection coupled with reliable isolation > 2 kV RMS.
Features
- High accuracy measurement capability (<±3%)
- Low power consumption (< 1mA at 276V AC/DC input)
- Flexible solution handling AC and DC input voltages from 15V to 276V
- Excellent long term reliability with digital isolation included
- Provides option for wetting current control
- This design is tested and includes firemware, demo and design guide.
