The RLX8 draws its power from the same power supply as the SPLat controller board it is attached to. It must be powered off the same power supply.

Do not attempt to power the RLX8 board off a different power supply than the SPLat controller. It will not work, and could damage either or both boards.

The board uses 12VDC relay coils. Associated with each relay is a 12V regulator chip. This ensures that even on a 24VDC system power supply the relay coils will not overheat.

The minimum system supply voltage recommended to ensure reliable relay operation is 15VDC.

Each relay circuit, when activated, draws a maximum of 47mA, independent of the supply voltage. You therefore need to budget that much, times the maximum number of relays your program will turn on simultaneously.
