ECT 284 Week 2 Homework

Chapter 2, p. 49: Problems 1, 4, and 5

1. A discrete 120 V ac output module is to be used to control a 230 V dc solenoid valve. Draw a diagram showing how this could be accomplished using an interposing relay.

4. Create a typical five-digit address (according to Fig 2-4) for each of the following:

5. Assume the triac of an ac output module fails in the shorted state. How would this affect the device connected to this output?
