Discrete Output Devices
Which of the following are discrete output devices?
(a) Motor Magnetics & pushbuttons
(b) Limit Switches & Control relays
(c) All Of The choices listed
(d) Solenoid valves & thermocouples
(e) Motor magnetics & pilot lights.
This is what i understand so far concerning Discret Output Devices.
Discret Output devices fall into a list of devices such as
- Control Relays
- Alarms
- Valves
- Motor Starters
- Solenoids
- Fan's
- Lights
Which in a PLC Module, it provides an interface between the CPU and the output componets like the ones I have listed.
My question Is what or Even If a THERMOCOUPLE falls into a discrete output device.
I know that a THERMOCOUPLE is a device which converts Temperature into Voltage.
With what I understand so far I know that the answers can not be A, B, Or C, my gut feeling is leaning towards D.
Some help on this Would be greatfull !!!!
