Wiring Diagram Details
Power Supply
The power supply section of the wiring diagram includes two terminals: L1 and N. L1 is the live wire, while N is the neutral wire. These wires are used to connect the controller to the electrical supply.
It is important to note that the 2707a L requires a stable power supply, with a voltage range of 85-264 VAC. If the voltage supply is unstable, it can cause the controller to malfunction or even fail.
Input
The input section of the wiring diagram includes three terminals: T+ and T- for the temperature sensor, and C for the cold junction compensation. These terminals are used to connect the temperature sensor to the controller.
The temperature sensor can be either a thermocouple or a resistance temperature detector (RTD). The wiring for each type of sensor is slightly different, but in general, the T+ wire is connected to the positive terminal of the sensor, while the T- wire is connected to the negative terminal of the sensor.
The C terminal is used to connect the cold junction compensation circuit, which is used to compensate for temperature variations in the wiring between the sensor and the controller.
Output
The output section of the wiring diagram includes two terminals: H and L. These terminals are used to connect the controller to the heating, cooling, or alarm devices.
The H terminal is connected to the positive terminal of the device, while the L terminal is connected to the negative terminal. The type of device that is connected to the controller depends on the application. For example, in a heating application, the device may be a heater coil or a heating element.
Communication Ports
The 2707a L has several communication ports, which can be used to connect the device to a computer or network. These ports include RS232, RS485, and Ethernet ports.
The RS232 port is a standard serial port that can be used to connect the controller to a computer or other device. The RS485 port is a serial port that is used for communication between multiple devices, such as in a network. The Ethernet port is used to connect the controller to a local area network (LAN) or wide area network (WAN).
