RLY ASSY contains of 3 phased array probe connectors and provides switchable connection between
probes and 64ch transmitters/receivers.
NOTE: There is no numeric order in the probe port, system recognizes the first probe slotted on the
port as the probe #1, regardless of the probe port location.
This board also has interface for a single CWD probe connector.
The main function of RLY ASSY is as follows.
