Data Loop Opto Coupler

The 81052 opto coupler provides asynchronous communication between processors. Using opto couplers on all data which is transferred between control centers greatly enhances lightning protection. Due to the fact that the optically coupled units have a 7500 volt electrical isolation between control centers allows for ground separation of the supply voltages. In addition, the 81052 provides asynchronous communication between the control centers. Therefore, each control center is allowed to operate on a locally generated clock and provides for independent operation of each control center. The 81052 optical isolator provides for complete electrical isolation with asynchronous data transfer.
