3.2. Digital Inputs
Digital inputs are typically used with electrical signals and switches that are either
on or off.
There are three types of digital inputs in the VMM2404:
Programmable Digital Inputs
Power Control Digital Inputs
Addressing Digital Inputs
3.2.1. Programmable Digital Inputs
The VMM2404 has 9 programmable digital inputs:
INPUT16_D through INPUT24_D.
The general purpose inputs can also be used as programmable digital inputs.
