PID Temperature Controller Instrument

XM series PID Temperature Controller instrument is a secondary instrument connected to on-site testing instruments such as thermocouples, rtd, and pressure transmitters. It is used to display measurement signals of on-site testing instruments, such as temperature, pressure, liquid level, flow, weight, etc. parameters about industrial processes. These measurement signals are processed and then output to the execution instrument for adjustment, alarm, and storage, or the data is transmitted to the computer system through means of electronic communication to achieve the purpose of automatic control and production management.

XM series PID Temperature Controller instrument has functions such as automatic cold junction compensation, automatic zero stabilization, universal input, configurable, electric communication, fault indication, power-down protection, and other functions. The display accuracy is ±0.5%F.S. A single instrument has a maximum of 24 input channels and a maximum of four alarm relay outputs. The digital display control instruments often go together with various auxiliary instruments (such as signal transmitters, isolators, amplifiers, operators, etc.) to form industrial automation instrument control systems.

Frequently Asked Questions

How to select the appropriate input and output types?

Answer: ① Input type: Select according to on-site sensors. Thermocouple/RTD sensors are directly connected to corresponding signals, and transmitter output signals select standard signals such as 4~20mA/0~5V; ② Output type: Select relay or SCR output for controlling heaters, 4~20mA constant current output for controlling frequency converters, and 0~24V output for controlling small actuators. It needs to match the signal requirements of the actuator.

How to choose between multi-channel and single-channel models?

Answer: For monitoring 1~4 parameters per device, select single/4-channel models with lower cost; for production lines and large equipment that need to monitor multiple parameters (more than 5 channels) simultaneously, select multi-channel models (maximum 24 channels) for centralized management, simplifying wiring and control cabinet space.

Will parameters be lost after power failure?

Answer: No. The product has a power-down protection function. Key information such as set PID parameters, alarm thresholds, and channel configurations will be automatically stored. After power recovery, there is no need to reset and it directly resumes working status.

How to solve the problem of excessive parameter fluctuations?

Answer: ① Optimize PID parameters (proportional P, integral I, derivative D) to reduce overshoot and oscillation; ② Check if the sensor installation is firm and if the signal is interfered. Shielded wires can be added or the installation position can be adjusted; ③ Confirm that the actuator is working normally to avoid parameter fluctuations caused by actuator failures.

Can it be connected to PLC or computer systems?

Answer: Yes. The product is equipped with RS232/RS485 and other communication interfaces, supporting standard industrial communication protocols. It can be directly connected to PLC, DCS, or computer systems to realize data upload, remote parameter setting, and control, adapting to the needs of industrial automation integration.

How to configure the alarm function?

Answer: Enter the alarm setting interface through the instrument operation buttons, select the alarm channel, set the alarm threshold (upper limit, lower limit, or interval alarm), and associate the corresponding alarm output terminal; after the alarm is triggered, the relay action can link the sound and light alarm or cut off the equipment power supply. The specific configuration needs to be combined with on-site safety requirements.
