I need help this is for my ELPT class

Troubleshooting is simplified in most PLC's because they include: 1. Fault Indicators 2. Fuse Blocks 3. Time delay relays 4. trouble lights QUESTION 4 Some manufacturers refer to the Processor section as the: 1. Binary Logic Counter 2. Main Brain 3. Master Processor 4. Central Processing Unit Click Save and Submit to scue and subnut. Click Saue All Ansurers to save all answe A PLC requires four main components. They are the Processor unit, the Power Supply, the Input/Output Section, and the: 1.Programming Device 2. Hand-Held Programmer 3. Laptop Computer 4. Network Controller QUESTION 6 The four main parts of a power supply are: The step-down Transformer section; The Full-wave rectifier section, The Voltage Regulator Section and : 1.

Optical isolation 4. Metal Oxide Varistors (MOV's) QUESTION 14 The is "on" when the input device is closed, and is "off" when the input device is open. 1. status light 2. pilot light 3. fault indicator 4. optical isolator A has filtering circuits to condition the low voltage signal and add an additional delay to the response time. 1. A.C. Analog input module 2. D.C. discrete input module 3. A.C. output module 4. Reed relay module QUESTION 16 The shields of twisted-pair device cables should be grounded ONLY at the PLC end, or in the main marshalling cabinet to prevent 1. Ground loops 2. Electrical Noise 3. Static 4. All of the above Output modules are generally classed as 1. Fixed 2. Modular 3. rack mounted 4. A.C. or D.C. QUESTION 18 "SOURCING" and "SINKING" indicate whether or not an I/O module is supplying current to the input device. 1. True. 2. False. 3. Only while operating. 4. Only when disconnected. When the load of a controlled device (large motor starter) is greater than the I/O module is rated for, we may use to increase the capacity of the control circuit. 1. reduced voltage starter 2. time delay relay 3. interposing relay 4. reactor or resistor QUESTION 20 Which of the following is NOT normally a source of harmful electrical noise: 1.
