This module provides the following IOs:
- 16 opto-isolated digital outputs (PNP, external voltage input 5-24V in two groups). Each output is capable of sourcing ~0.6A of current and has over-current protection.
- 16 opto-isolated digital inputs (12-24V, both sourcing and sinking connections are possible).
Due to slot width limitations, each group of outputs (4 in total) are fitted with spring-type pluggable terminal blocks (LCSC part number: C2908401).
VCC is 5..24V DC. Each of the output blocks has a separate power supply, so for example one block can be 5V outputs and another one- 24VDC.

Common input can be either ground, or positive voltage of 12..24VDC for sourcing or sinking type outputs.
Limited testing has shown that inputs also work at 5V output level, but that's not really guaranteed with the values of components in current design.
