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 s unlatched and de-energized. For ump up applications use normally closed input devices and switch the Dosition of "A" and "B."This device nust be located and grounded in a non-hazardous location.
