PLC Conveyor Motor Ladder Logic
Objective: The sequential tasks as follows
- When START button pressed
- Motor will be started
- RUN (Green Lamp) indication lamp will be activated
- Motor Running, so Box will start Move
- Proximity Sensor will detect when the box arrives at other end
- Motor will be stopped
- RUN (Green Lamp) indication lamp will be de-activated
- STOP (Red Lamp) indication lamp will be activated
- An Emergency Stop push button will be used to stop the motor at any time.
Relay Schematic
- R : STOP Indication lamp,
- G : RUN Indication lamp,
- M : Motor,
- OL : Overload Relay (Motor Protection Relay),
- LS1 : Proximity Switch,
- PB1 : Start push button,
- PB2 : Emergency Stop Pushbutton,
- CR : Contractor Relay
Operational Sequence
- Start button is actuated.
- CR1-1 closes to seal in CR1 or to latch the start command
- CR1-2 opens, switching the red stop pilot light off
- CR1-3 closes, switching the green run pilot light on
- CR1-4 closes to energize the motor starter and motor
- The box/package moves, and proximity switch (LS1) detects the box when it reached and de-energize coil CR1
- CR1-1 opens to open the seal-in contact ( unlatched start command)
- CR1-2 closes, switching the red pilot light on
- CR1-3 opens, switching the green pilot light off
- CR1-4 opens to de-energize the starter coil, stop the motor, and end the sequence

Start-stop motor control relay logic circuit.
By pressing start button coil relay for magnetic contactor (CR1) and green lamp energized (G). By pressing stop, it will de-energized the coil relay for magnetic contactor (CR1) and the red lamp will ON (R).
Please convert Relay Logic Circuit into PLC Logic Circuit through complete connection and details below by using the given inputs/outputs based on the given relay logic diagram.
(INPUT) Stop – I:0.0 , Start – I:0.1
(OUTPUT) CR1 – O:0.0 , G – O:-0.1 , R – O:0.2
Good Morning editorial team please kindly permit me the use of the PLC conveyor Motor ladder logic and Relay schematic in a Journal Article am working on with my HE student and Co-lecturer .
Hope to hear from you
Kind Regards
Design PLC ladder diagram for conveyor choosing system.
An operator should be able to operate the system in the manual mode using four push button on switches and a common off switch.. The company is producing four different types of products which are categorized in blue, green, yellow and red colors for identification. These products are to be transported through different conveyors for further process.
In the four output signals to control the system, only one output signal is supposed to be on at a time. If the operator tries to switch conveyor, the previous output should go OFF and the chosen conveyor output should be turned on.
