Latching
Relay
The ISRL has two independent outputs to the hazardous
area and one (dry contact) relay output with a latching
function. The outputs can be switches or, when used
with a conductive liquid, electrodes. For pump down
when output "A" is completed (contact closed or
low resistance), 1 second later LED "A" turns On
and the dry output contact is energized.
When
output "B" is completed (contact closed or low resistance),
1 second later LED "B" turns On and the dry output
contact is unlatched and de-energized. For pump
up applications use normally closed input devices
and switch the position of "A" and "B."This device
must be located and grounded in a non-hazardous
location.
