SunYuan DIN 1X1 ISO U/A-P-F (LED1) series intelligent isolation converter is an intelligent transmitter that converts the analog DC voltage or current signal into the linear pulse frequency value according to the change ratio of the input value. The product integrates isolation, display, alarm control and transmission. It contains a set of high efficiency and multi-isolated DC/DC power conversion circuit, V/F conversion circuit, interference suppression circuit, signal coupling isolation conversion circuit, display and alarm. Control circuits, etc., are widely used in frequency modulation, phase modulation, analog-to-digital converters, digital voltmeters, data measuring instruments, and remote telemetry remote control devices. The product's internal integrated process structure and new technology isolation measures enable the device to achieve: power supply, signal input / output 3000VDC three isolation, and can meet the industrial requirements of wide temperature, humidity, vibration, the harsh working environment. This intelligently designed new isolated transmitter series has built-in reverse protection, overload, anti-surge and other protection circuits. It adopts standard DIN35 rail installation method, which is convenient for users to use on site.
      The DIN 1X1 ISO U/A-P-F (LED1) series is intelligently designed to provide a variety of functions not found in traditional products. The analog DC voltage and current signals can be isolated from the frequency pulse signal by a single power supply, and displayed in decimal digital quantities according to the set range. The traditional embedded analog display meter is adjusted by a potentiometer, and the adjustment parameters are single, inflexible, and greatly affected by temperature. Compared with the traditional analog display table, the embedded intelligent digital display table is operated by two key combinations, which are controlled by the central processing unit CPU, and can realize various parameters such as zero point, full scale, decimal point, alarm, delay and the like. Settings, with strong flexibility and practicality. The digital display adopts an LED display panel and has reverse and overcurrent protection functions. The products are widely used in the monitoring and control of analog control points in remote measurement and control, aerospace, communications engineering, environmental protection, intelligent transportation and other industries.
      DIN 1X1 ISO U/A-P-F (LED1) series intelligent monitoring and isolation transmitter can directly change the analog DC voltage and current signal into its linear digital frequency pulse signal display control transmission, and has signal display and output alarm control functions. The embedded intelligent digital display meter is used to measure the transmission signal. The displayed digital value is not a direct input voltage or current measurement value, but a signal preset value. By setting the measured input zero point and full-scale voltage or current value relative to each other. These two preset values ​​are displayed linearly. For example: the transmission input 4-20mA, 4mA is set to 0, 20mA is set to 8000, then the meter will display 2000 when input 8mA, 4000 will be displayed when input 12mA; and if the 4mA is set to 1000, 20mA is set to - 1000, the table will display 0 when 12mA is input, and -500 will be displayed when 16mA is input. The maximum display range of the digital display is 9999, which is four digits; the minimum is -1999. Its alarm function with two isolated switch outputs can display, control and alarm on the spot. The two alarm points set have positive and negative alarm direction settings. The alarm object of the alarm point is for the display reading. The last decimal point of the LED panel flashes during the alarm, and the alarm information is isolated and output by the digital optocoupler. For products that need to set the alarm function, the upper or lower limit alarm value and alarm mode can be modified by the programmer. For detailed setting method, please refer to the “Display Table User's Manual” on the following page.
Remark: The alarm signal is the OC gate (open collector) output. For the specific application, please refer to the [Alarm Output and Application] on the following page

Alarm output and application:
1. The DC level signal generated by the two-way alarm signal in the main CPU chip is isolated and output by the optocoupler. The output low level indicates the alarm state, and the output high level is the non-alarm state.
2. Because the display controller is passive two-wire system, the minimum working current is 3mA, so the alarm signal is also very weak, the minimum is only 0.5mA. The signal is isolated by a phototransistor type photocoupler with a strong current spreading capability, and an open collector (OC gate) output is used. The output is connected to the pull-up voltage, and the current can be expanded up to 120mA. The principle of this phototransistor type photocoupler is shown in the figure below: the instrument signal is isolated by optocoupler, 9, 10 "1H /1L", 7, 8 "2L /2 H" wiring port is optocoupler OC gate The output end of the signal is connected to the external power supply circuit of the instrument, and further amplifies and energizes the alarm signal, and finally reaches an actuator that can drive the required sound, light, electricity, refrigeration, heating, and motor. 9, 10 "1H / 1L" is the first alarm output, 7, 8 "2L /2 H" is the second alarm output, "1H", "2H" connected to the phototransistor collector, "1L", "2L emitter.
