12 A discrete relay type output module can be used to switch either AC or DC load devices. Why? OIt uses complex circuitry to convert AC signals to DC signals so that it can handle either type of output. O All output cards can be utilized 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. O 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 O It 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 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.

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds.
