Two Channel Intrinsically Safe Relay

The ISR2 has two independent outputs to the hazardous area and two independent (dry contact) relay outputs. The outputs to the hazardous area can be switches or, when used with a conductive liquid, electrodes. When output "A" is completed (contact closed or low resistance), 0.5 second later the dry output contact "A" is closed and the "A" LED turns On. When output "A" is opened (contact opened or high resistance), 0.5 second later the dry output contact "A" opens and the "A" LED turns Off. "B" operates the same way, but is independent of "A." There is also a supply power LED indicator. The ISR2 must be located and grounded in a non hazardous location.
