Latching Relay

Latching RelayLatching relays work by having 2 sets of coil contacts used to actuate the state of the relay. When one set of coil contacts is energized, the relay switches over to its normal energized state and holds its position even if power is removed from the relay coil. It is not until the other set of coil contacts is energized, that the relay resets back to its original electrical state. Refer to the diagram to see which pins are used to actuate the relay.

1800/1801 Maintenance

5 GPM indicators must be installed horizontally in a vertical pipe run with the flow direction up

Calibrated on increasing flow

They can handle pressures up to 400 PSI at 72°F

The switch wire is 22 AWG

Because we mold in-house

this is the unit for you

Flow rates below the set point do not effect the unit and do not cause it to actuate

This is the same as our original 45325-B except it has been improved with our patented straight through flow module with spoked orifice that creates laminar flow to increase set point accuracy and enhance self-cleaning

simply cut paddle for the appropriate set point listed
