Question 14
Ullized across various types of loads, without concern for voltage type or amplitude.
OIt uses an electromechanical relay element for switching which allows it to work for either AC or DC applications.
Since AC is just an alternating form of DC, all AC output modules can be utilized for switching either AC or DC.
QUESTION 13
Explain the purpose of a redundant PLC processor.
O It allows the output modules to carry more current by utilizing two or more PLC's
OIt allows one processor to carry out one task on the same equipment and the other to carry out a different task on the same equipment
O It is a great way for the installer to double their installation costs
O It allows transfer of control to the second processor in the event of a processor fault.
