The SunYuan DIN 1X1 ISOEMH (LED1) series is intelligently designed with features not found in traditional products. The analog signal can be isolated and transmitted only 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, this intelligent digital display table is operated by two key combinations and controlled by the central processing unit CPU, which can realize setting of various parameters such as zero point, full scale, decimal point, alarm and delay. , with strong flexibility and practicality. The digital display adopts an LED display panel and has reverse and overcurrent protection functions. Products are widely used in high-speed rail, subway 750V/1500V track voltage isolation monitoring, power instrumentation and sensor signal transmission and reception and monitoring, high-voltage inverter signal remote anti-interference and distortion-free transmission, grid transformer equipment operation signal detection, isolation and long-distance transmission, power monitoring , medical equipment isolation barrier.
 
         DIN 1X1 ISO EMH (LED1) series of intelligent high-isolation transmitters are display control transmitters that amplify, convert, and convert analog voltage or current signals into high precision and linearity. The product integrates isolation, display, alarm control and transmission. It contains a set of high efficiency and multi-isolated DC/DC power conversion circuit, signal modulation and demodulation circuit, signal coupling isolation conversion circuit, display and alarm control circuit. Especially suitable for: 0-75mV/0-5V/0-10V/0-1mA/0-20mA/4-20mA and other analog unregulated isolation amplification transmission, display and control. The product adopts a low-cost solution of magnetoelectric coupling, and is mainly used in applications where there is no special requirement for EMC (electromagnetic interference). The internal integrated process structure and new technology isolation measures enable the device to achieve: auxiliary power supply, signal input and output 6000VDC three isolation. And can meet the industrial requirements of wide temperature, humidity, vibration environment. Intelligent design of the new high-isolation transmitter series products built-in reverse connection, overload, anti-surge and other protection circuits, no external components, zero-point gain adjustment, standard DIN35 rail installation, convenient for users to use on-site.
  
         DIN 1X1 ISOEMH (LED1) series of active intelligent isolation transmitters can directly isolate and convert analog signals, and have 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 output voltage or current measurement value, but a signal preset value. By setting the measured output zero point and full-scale voltage or current value relative to each other. These two preset values ​​are displayed linearly. For example: the transmission output 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.


3. Because of the limitation of the maximum current of the phototransistor Ic, its expansion and driving load capacity is limited. If the user needs more driving current, it can be used to drive relays, solenoid valves, stepping motors and other devices on site, and can externally connect the power expansion circuit. The power amplifier tube or servo circuit is subjected to current amplification and special processing.
