The DB-24PR is a 24-channel power relay output board consisting of 8 Form-C
and 16 Form-A electromechanical relays for efficient programmable control of
the load switching. The contact of each relay can allow a 5 A current load at 250

. The relay is powered by applying a 5 voltage signal to the
associated relay channel on the 20-pin flat-cable connector (only uses 16 relays)
or 50-pin flat-cable connector (OPTO-22 compatible, for DIO-24 series). 24

LED is light when their associated relay is activated. To avoid overloading your
PC’s power supply, this board needs a +12 V
