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.
2. Assume a thermocouple generates a linear voltage of from 20 mV to 50 mV when the temperature changes from 750°F to 1250°F. How much voltage will be generated when the temperature of the thermocouple is at 1000°F?
3. Assume the triac of an ac output module fails in the shorted state. How would this affect the device connected to this output?
