» Functional Description
The DB-24SSR includes 24 normally open, Form A, solid- state relays.
The board acts as an interface to field logic signals and can eliminate ground-loop problems and isolate the host computer from damaging voltages.
The user can use the DB-24SSR to switch high voltage load which can be up to 250VAC and up to 4 A.
The relay is energized by appling a 5 volt signal to the appropriate relay channel via a 50-pin OPTO-22 compatible connector or a 37-pin D-Sub connective.
Twenty-four enunicator LEDs, one for each relay, light when their associated relays are activated.
