The YRI-41 is a direct connected current proving switch available in five different adjustable ranges, 1mA-100mA, 10mA-1A, 30mA-3A, 50mA-5A, 100mA-10A. External current transformers cannot be used with the YRI-41. The current is monitored on its own supply hence a separate auxiliary supply is not required.
Note, the monitored load and the supply voltage must be from the same source and of the same voltage potential, please note carefully the circuit diagram.
On connection of the supply/load the green LED illuminates, should the load exceed the adjustable set point the SPCO relay output will energise and the red LED will illuminate. Should the load then fall below the set level, less than a nominal 1% hysteresis the output relay will de-energise and the red LED will be extinguished.
