> Two channel relay w/ intrinsically safe outputs ISR2
Two channel relay w/ intrinsically safe outputs ISR2
outputs to the hazardous area and
two independent (dry contact) relay
outputs. The outputs to the hazardous
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 “Aâ€
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 nonhazardous
