WIRING CP1E Panduan Praktis Basic Wiring PLC OMRON CP1E untuk Pemula!

Summary

In this video, Eko Aris from the Mechatronics Study Program at Sanata Dharma University provides an in-depth guide on wiring the Omron CP1E PLC. He explains the proper connections for both DC and AC power inputs, the importance of selecting the correct sensors (PNP or NPN), and how to wire digital inputs. The video also covers relay and transistor output types, emphasizing their limitations, such as the maximum current rating. Eko concludes by discussing the essential steps to ensure proper PLC function, including the connection of motors and other advanced systems, making it a valuable resource for anyone working with PLCs.

Takeaways

• 😀 Ensure the power supply is connected correctly: for DC, use plus and minus connections, while for AC, make sure the appropriate AC voltage is applied.
• 😀 For input connections, buttons should be connected to the positive (for DC) or negative (for NPN) terminals, depending on the type of sensor used.
• 😀 PNP sensors require positive power, while NPN sensors require negative power. Be careful to connect them correctly to avoid issues.
• 😀 Always fill the input terminals correctly; do not leave any input connections unfilled to ensure proper PLC function.
• 😀 When using relay outputs, remember they can handle both AC and DC. However, the maximum load for relay outputs is 2 amps. Anything more requires a driver.
• 😀 Transistor outputs can only handle up to 0.3 amps and must be connected to DC power. They are not compatible with AC power.
• 😀 Relay outputs can be reversed for AC or DC devices (e.g., lights), but transistor outputs cannot be reversed, so make sure to wire them correctly.
• 😀 Ensure proper load handling when using relay outputs. If the load exceeds 2 amps, a driver circuit is necessary to avoid damaging the PLC.
• 😀 For transistor outputs, be mindful not to exceed the current rating of 0.3 amps. Overloading can damage the transistor.
• 😀 Always check the specifications of both the PLC and the connected components to ensure they are compatible and that the wiring is correctly configured.

Q & A

What is the primary focus of the tutorial presented by Eko Aris?

The primary focus of the tutorial is on the wiring of the Omron CP1E PLC, explaining how to properly connect various devices such as sensors, buttons, and outputs like relays and transistors.

What does the last code 'D' indicate for power supply connections?

When the last code is 'D', it indicates a DC power supply, and the power connections must be made with a plus (+) and minus (-) terminal.

How should AC power be connected to the Omron CP1E PLC?

When the last code shows 'A' for AC, it means the PLC should be connected to an AC power source, with appropriate AC wiring.

What is the difference between NPN and PNP sensors in terms of wiring?

PNP sensors are connected to the positive terminal (plus) for DC wiring, whereas NPN sensors are connected to the negative terminal (minus) for DC wiring.

What should be considered when wiring buttons to the PLC?

When wiring buttons to the PLC, ensure that the button is connected to the positive terminal (+) in DC configurations.

How does a relay output differ from a transistor output in the Omron CP1E PLC?

A relay output can handle both DC and AC loads and supports higher amperage (up to 2 amps), while a transistor output is limited to DC loads and has a lower current capacity (up to 0.3 amps).

What is the maximum current rating for relay outputs in the Omron CP1E PLC?

The maximum current rating for relay outputs in the Omron CP1E PLC is 2 amps. Exceeding this limit requires a driver to handle higher currents.

What is the maximum current rating for transistor outputs in the Omron CP1E PLC?

The maximum current rating for transistor outputs is 0.3 amps. Exceeding this limit may cause damage to the transistor output.

Can the polarity be reversed for transistor outputs in the Omron CP1E PLC?

No, the polarity for transistor outputs cannot be reversed. Unlike relay outputs, transistor outputs are designed for DC loads and do not support reversed polarity.

What are the key factors to consider when connecting sensors to the Omron CP1E PLC?

The key factors include ensuring the correct sensor type (PNP or NPN), proper polarity for DC sensors, and understanding the power requirements of the sensor for proper connection.
