SOI

Single phase Power Solid State Relay with status output: Load Currrent

OPERATION: By applying or removing a voltage on the control input, the SOI relay switches or interrupts the current in the load. If the value of the load current is greater than the threshold that was preset in the factory, the current transformer included in the SOI will close the contact for signalling. It therefore indicates that a current is flowing into the load and leaves the user or the system to interpret this status.

ADVANTAGES :

• Reduction of quantity, cost and time of wiring
• Elimination of the need to pass the power cables through a current transformer
• Elimination of costly analogue inputs on the PLC
