ICP DB-24R/24 24-Channel OPTO-22 Compatible Relay Board (24V)

24-Channel OPTO-22 Compatible Relay Board (24V). The DB-24R consists of 24 form C, electromechanical relays for efficient switching of load by programmed control. The contact of each relay can control a 0.5 A /110 V load or 1A / 24VDC. The relay is energized by applying a 5 voltage signal to the appropriate relay channel on the 50-pin Opto-22 compatible connector or D-Sub 37 connector . Twenty-four enunciator LEDs, one for each relay, light when their associated relay is activated . This board needs a +12VDC or +24VDC external power supply to avoid overloading your PC’s power supply.
