2.3.7 DB-24PR Power Relay Board
The DB-24PR, 24-channel power relay output board, consists of 8 form C and 16 form A
electromechanical relays for efficient switching of load programmed control. The contact of
each relay can control a 5 A load at 250 V
AC
/30 V
DC
. The relay is energized by applying a 5
voltage signal to the appropriate relay channel on the 20-pin flat cable connector (just used 16
relays) or 50-pin flat cable connector. (OPTO-22 compatible, for DIO-24 series.) Twenty - four
enunciator LEDs, one for each relay, light when their associated relay is activated. To avoid
overloading your PC’s power supply, this board needs a +12 V
DC
or +24 V
DC
external power
supply.
