| How to extend the PCLD-782/B input range to 33V? | |||
|---|---|---|---|
|
Solution:
The input resistors of PCLD-782/B (RA0 - RA23) are 560 ohm. This resistance restricts the input range from 5V to 24V. There are two ways to extend input range to 33V:
1. Change the input resistor to 1.5K ohm (1W), or
2. Cascade a 1K ohm (1W) resistor at the input terminal
