Title: Module 2 - Programming Challenge (One for Chapter 2 & Two for Chapter 3)
Course: Open EIC225 Programmable Controllers > Section: Module 2: Hardware Components, Number Systems and Codes

Action Required - Carefully read the directions for each challenge below!

From Chapter 2

1. A discrete 120 VAC output module is to be used to control a 230 VDC solenoid valve. Draw a diagram
showing how this could be accomplished using an interposing relay. (List of drawing tools available in the Module 1 Programming Challenge.)

From Chapter 3

1. The following binary PLC coded information is to be programmed using the hexadecimal code. Convert
each piece of binary information to the appropriate hexadecimal code for entry into the PLC from the
keyboard.
a.  0001 1111
b.  0010 0101
c.  0100 1110
d.  0011 1001

2. The encoder circuit shown in  Figure 3-17 is used to convert the decimal digits on the keyboard to a
binary code. State the output status (HIGH/LOW) of A-B-C-D when decimal number
a.  2 is pressed.

b.  5 is pressed.

c.  7 is pressed.

d.  8 is pressed.

When you have finished the above, you should have SEVEN responses to this challenge. Save your work upload your file or depending on the challenges above, upload the program files or link to the file (make sure I can access it!), I will evaluate your results and give you a grade and feedback in your Canvas Grades.
