4CHPROR3 Contact Ratings

Hello,


Please can the contact ratings for each channel be provided. Previous questions on Amazon has come back with the following response:

Voltage Range: AC: 100-240V; DC: 9-23V
Max. Load: 10A/2200W/Gang; 40A/8800W/Total


I've read this to be the input voltage range of the controller not the individual channel properties. My understanding is that each connection on a channel (NC/NO/COM) is independent of the controller input voltage therefore a different voltage can be switched i.e. controller is supplied by 240VAC but the controller could be switching 12VDC. I would like to switch up to 48VDC, hence the question. I would assume this would be the contact rating of the relays.
