ABSTRACT:
A logic isolation circuit with high transient immunity has a link-coupled transformer assembly for providing isolation. An input circuit provides pulses that indicate rising and falling edges, and an output circuit on the isolated side of the barrier converts the signal with pulses back into a digital logic signal with rising and falling edges. An interrogation feature allows the output to be updated frequently. The logic isolator can be provided in a single module for use in a process control board, or it can be provided as multiple parts for mounting on a circuit board.
