4What are the three main components of an electro-pneumatic system?
- APower Supply
- BRelay
- CLoad
- DSwitch Element
5A direct circuit means the system uses a relay
- AVerdadero
- BFalso
6A load consumes power meaning it requires a POSITIVE input and NEGATIVE output
- AVerdadero
- BFalso
7A switch is load
- AVerdadero
- BFalso
8What is the function of a solenoid?
- AControl Open/Close Valves
- BControl Relays
- CControl Contactors
- DAll are correct
9Fill in the blanks with monostable or bistable:
A push button is [blank_start]monostable[blank_end] and a control switch is [blank_start]bistable[blank_end]- Amonostable
- Bbistable

- A3
12which is NOT a sensor
- ALimit Switch
- BControl Switch
- CReed Switch
- DOptical Switch
13A Proximity Switch is actuated by a machine part where as
a Limit Switch requires no external contact- AVerdadero
- BFalso
14Which proximity sensors are electrically actuated
- AOptical
- BInductive
- CReed
- DCapacitive
15Reed switches are actuated when a magnetic field is present
- AVerdadero
- BFalso
16Check all the type of optical sensors
- ADiffuse reflective sensor
- BOne Light way Barrier
- CRefraction optical sensor
- DReflective light barrier
17Which are NOT true about Relays
- AThe contacts are usually Normally Closed
- BIt is a load
- CHigh voltage is applied to control another circuit
- DThe armature in the relay is attracted to solenoid coil when there is a magnetic field present
- EIt generates a controlled signal
18On a Time Delay, 1 means ON and 0 means OFF
- AVerdadero
- BFalso
19A Pull in Time Delay Relay means the first event occurs while the contact of the relay is delayed for a bit then it's activated.
- AVerdadero
- BFalso
20Drop Out Time Delay Relay means the first event AND the contact of the relay are activated at the same time. However, once the first event is off, the contact of the relay is still ON
- AVerdadero
- BFalso
21The Pole is the [blank_start]input[blank_end] terminal and the Throw is the [blank_start]output[blank_end] terminal
- Ainput
- Boutput
22The number of Poles = The number of SEPARATE circuits
- AVerdadero
- BFalso
23The number of Throws = The number of input connections
- AVerdadero
- BFalso

One Spring- AVerdadero
- BFalso
25In a DIN circuit, a Contact is drawn the same as a Switch
- AVerdadero
- BFalso
26In a JIC or DIN circuit with a load and switch, the load is drawn FIRST (near +24v) then the switch is drawn next.
- AVerdadero
- BFalso
27In an OR operation
1 + 1 =- A2
- B1
- C0
28In an NAND operation,
1 * 0 =- A0
- B1
29In a NOR operation,
1 + 1 =- A1
- B0
- C2
301* 0 =
- A0
- B1
31A * A (bar) =1
- AVerdadero
- BFalso
32A*1 = A
- AVerdadero
- BFalso
33A+1=1
- AVerdadero
- BFalso
34De Morgans Law
Bar all over (A+B) = Bar all over (A*B)- AVerdadero
- BFalso
35which are true about a Dominant ON circuit
- AIf the ON and OFF switch are pressed at the same time, the circuit is still energized
- BIf the ON button is pressed then released, the relay remains energized
- CIf the ON button is pressed then released, the relay is NOT energized
- DOnce the ON button is pressed then released, the OFF button is meant to stop the relay from being energized
36In a Dominant OFF circuit which are true
- Aif the ON and OFF switch are pressed at the same time, the circuit is not energized
- BIf the ON button is pressed then released, the relay is energized
- Cif the ON and OFF switch are pressed at the same time, the circuit is still energized
371+0+1+0+0+1=
