» Functional Description
The DB-24PR/24PRD is a 24-Channel power relay output board which consists of 8 form C and 16 form A electromechanical relays for efficient switching of load by programmed control.
The contact of each relay can control a 5 A load at 250VAC/30VDC.
The relays are energized by applying a 50-pin OPTO-22 compatible connector , a 37-pin D-sub connector or a 20-pin flat cable connector.
Twenty-four enunciative LEDs, one for each relay, light when their associated relays are activated.
To avoid overlading your PC's power supply, this board needs a +12VDC or +24VDC external power supply.
