Great news, this is just what I need.
I have a few questions:
- The video on Youtube mentions a 32 channels version of it. What is the status of that one?
- Does the documentation exist already (the RS485 part is present, but not the rest)?
- What are the power supply requirements for the module? I understand this can be 12 to 24 V. But what are the power needs (A) ?
- Can the module be inserted in a standard electrical cabinet (where only the prominent front part is visible, and all connections are hidden behind the cover) ?
Thanks in advance,
Laurent
