Introduction to PIM Panel Mount Isolated Smart Transmission Meters
SunYuan PIM-ISO U-P-D-Q-LED7 Series Panel Embedded Analog Isolated Transmitter and Transmitter is intelligently designed with a variety of functions that are not available in traditional products .Intelligent Transmission Meter can convert standard analog quantity into 0%-100% duty cycle output and display the analog quantity in decimal digital quantity according to the set range in linear correspondence. This embedded intelligent digital display meter is operated by a combination of two buttons and controlled by the CPU of the central processor, which can realize the setting of various parameters such as zero point, full scale, decimal point, alarm, time delay and so on, which is highly flexible and practical. Intelligent variable meter internal embedded installation of basic functions and extended functions of the two multi-function board, the product output is mainly for DC motors and stepper motors speed control and industrial site lighting brightness adjustment and design, the product can not only output 0%-100% of the PWM signal after the normal power on, but also the speed of the motor or the brightness of the light real-time display, the utility and intuitively strong, and comes with a communication interface can be communicated with the computer through the USB cable, the user can be based on their own actual situation will be the communication interface and their own industrial system configuration networking to realize the intelligent data management. The internal integration process and new technology isolation measures enable the device to achieve 2500VAC isolation voltage and industrial grade wide temperature, humidity and vibration field harsh environment requirements. This new generation of low-cost, small volume, multi-functional intelligent isolation transmitter instrumentation, with industrial field signal conversion, anti-jamming isolation, display and control of a variety of functions, is widely used in motor speed control, lighting regulation, metallurgy and mining, petrochemical industry, electric power equipment, medical instruments, industrial automation, new energy facilities and military scientific research and other fields.
PIM-ISO U-P-D-Q-LED7 products are mainly used for the isolation of analog voltage and current signals and display control, in the field of motor speed control and lighting regulation used more. Its embedded digital display meter is used to measure the input voltage and current signals. Since the signals correspond linearly, it can indirectly display the physical quantities that the user wants to monitor, such as the speed of the motor, the brightness of the light, the flow rate of the liquid level, and the duty cycle of the PWM, etc., and also has the function of outputting the alarm control. The embedded intelligent digital display meter displays numbers not as direct signal measurements, but as preset values of the signal, and the zero and fullness values of the measured signal are linearly displayed relative to these two preset values through the settings. For example, if the signal input is 4-20mA, 4mA is set to 0, and 20mA is set to 8000, then the meter will display 2000 when 8mA is input, and 4000 when 12mA is input; and if 4mA is set to 1000, and 20mA is set to -1000, then the meter will display 0 when 12mA is input, and -500 when 16mA is input. The maximum display range of the digital display meter is 9999, i.e., four digits; the minimum is -1999. Its alarm function with two isolated switching outputs can be displayed, controlled and alarmed locally. The two set alarm points have positive and negative alarm direction settings. Alarm point of the alarm object for the display readings, alarm LED panel last decimal point flashes, alarm information through the digital optocoupler isolated output alarm signal. For products that need to set alarm function, the upper limit or lower limit alarm value and alarm mode can be modified by the programmer, please refer to the "Variable Transmission Meter Software Setting Instructions" on the back page for detailed setting method.
Note: The alarm signal is an OC gate (open collector) output, please refer to the description of [Alarm Output and Application] on the back page for the specific application.
