Title: Mitsubishi PLC Temperature Controller Schematic and Wiring Diagram
This article introduces the schematic and wiring diagram of Mitsubishi PLC temperature controller. The temperature controller is an important device for controlling the temperature of industrial processes. It can be used to monitor and control temperatures in various industrial applications, such as in machine tools, metal processing, and plastic molding. The schematic and wiring diagram show how to connect the temperature controller to Mitsubishi PLC, as well as how to set up and test the system. The article also provides a brief overview of the temperature controller's functions and how it operates.
Introduction:
Mitsubishi PLC (Programmable Logic Controller) temperature controllers are widely used in industrial automation applications to monitor and control temperature levels. They provide precise temperature control by integrating with sensors, heaters, and other components of a process system. In this article, we will explore the schematic and wiring diagram of a Mitsubishi PLC temperature controller to help you understand its working principle and how to install it in your system.
Schematic Diagram:
The schematic diagram of a Mitsubishi PLC temperature controller typically includes the following components: sensor, heater, relay, and the PLC itself. The sensor is connected to the PLC to provide real-time temperature data. The heater, which is controlled by the PLC, is used to heat up the system or maintain a specific temperature level. The relay is used to switch the heater on or off based on the PLC's instructions.
1、Sensor: The sensor is connected to the PLC to provide real-time temperature data. It measures the temperature of the system and sends this information to the PLC for processing.
2、Heater: The heater is controlled by the PLC to heat up the system or maintain a specific temperature level. When the PLC receives a signal from the sensor indicating that the temperature has dropped below a set point, it will send a signal to the heater to turn on. Once the temperature reaches the set point, the PLC will send a signal to turn off the heater.
3、Relay: The relay is used to switch the heater on or off based on the PLC's instructions. It receives signals from the PLC and acts as a switch to control the power supply to the heater.
4、PLC: The PLC is the brain of the temperature controller. It receives temperature data from the sensor, processes it, and sends control signals to the heater and relay to maintain the desired temperature level.
Wiring Diagram:
The wiring diagram of a Mitsubishi PLC temperature controller shows how these components are connected together. The sensor is connected to the PLC via a wire or cable. The heater is connected to the PLC via another wire or cable, and it also receives power from a separate power supply unit (PSU). The relay is connected to both the PLC and the heater, providing a path for current to flow when needed.
1、Sensor Connection: The sensor is connected to the PLC using a wire or cable with two conductors (positive and negative). These conductors carry current from the sensor to the PLC, allowing the PLC to read real-time temperature data.
2、Heater Connection: The heater is connected to the PLC using another wire or cable with two conductors (positive and negative). This wire carries current from the PSU to the heater when needed, allowing the heater to operate and heat up the system or maintain a specific temperature level.
3、Relay Connection: The relay is connected to both the PLC and the heater using wires or cables with two conductors (positive and negative). These conductors provide a path for current to flow from the PLC to the relay, allowing it to receive control signals from the PLC and control power supply to the heater accordingly.
Conclusion:
The Mitsubishi PLC temperature controller schematic and wiring diagram are essential for understanding its working principle and installation in your system. By following these diagrams carefully, you can ensure that your temperature controller operates correctly and provides precise temperature control for your industrial automation application.
