Chaz For the sake of clarity please be aware that the word grounding is not always the same as 0V. Grounding usually what is referred to as the star point ie earth. OV is the -ve from the power supply (but is not always at earth potential). ..Clive

Thanks, understood, will be careful with the terminology in future for the sake of clarity.

Chaz the Cslabs Controller outputs are PNP logic so you can't control 0v only Load. So change the relay around and provide it with Positive.
The way the outputs work is you provide 24V and 0v to each bank of 4 outputs. Then each output switches the Load. The Load must share the 0v of the Output.

It's similair with Inputs as well except that each individual Input is provided with 24v & 0v but you can choose which to sense. So can use NPN or PNP logic if required.

The HV option could be used for enableing the drives but again it just uses an Output so will be PNP logic.
Low active just changes how it reacts or switches and doesn't inverse the voltage etc. IE: Active if Voltage goes High(24v) or Active if voltage goes Low(0v)
Or in case of outputs If OUTPUT High Turn it Low when active and vise versa.!

EDIT: If controlling relay with OUTPUT make sure the relay coil load isn't more than 250mA otherwise you'll damage the OUTPUT.
