a plc output module, that is specified to switch 120 VAC at 1 Amp max, will probably contain which of the following in its output circuit:
a- power transistor
b- triac
c- diode
Homework Answers
Diode and power transistor are typically used for DC load drive therefore it can not be used for AC load devices. While Traic is a three terminal electronic component used for AC driving device. Hence option (b) is correct.
Note- please find me in comment box if you find any difficulty. Good luck
