1

Up to 24 V

2

The transient voltage protection is designed to clamp low energy voltage events. High energy voltage events may overheat and destroy the input protection

3

Bit-rate list: 5k, 10k, 20k, 33.333k, 47.619k, 50k, 83.333k, 95.238k, 100k, 125k, 250k, 500k, 800k, 1M

9

Full frequency (16 kHz) pulse input assumes a perfect sine. If this is not the case, the max frequency may be lower.

10

The input channels share input range in pairs of two
