SunYuan SY LED6 Digit display meter is a current voltage meter with wiring socket used in transmitter measuring circuit. It can display current voltage signal (0~5V, 0~10V, 1~5V, 0~±200mV, 0~20mA, 4~20mA, etc signal) in linearity and in decimal base based on the pre-setting range. That LED display meter operates in equal and stable brightness and its LED panel is driven by constant
current. It has reverse polarity and over current protection circuit, and widely used in temperature, pressure, flow, level signal controlling and monitoring system in industrial site, oil industry, environment monitoring, mining industry, etc. Usually, the temperature sensor, pressure sensor, flow sensor, level sensor signal are converted into standard voltage current signal, and then connect it into that LED meter to display the sensor signal to make it easy to monitoring and controlling. There are two types of connection: 2-wire passive connection, it is applied for 4-20ma signal, no external power supply required. 3-wire active connection, it is applied for 0-5V, 0-10V, 1-5V, 0-20mA, etc signal, external power supply required, the power supply can be 5V, 12V, 15V, 24V. There is 2 buttons on the backside of the panel meter; it is used to set zero, span, decimal points, alarm, delay, etc parameters.The input signal and the digits displayed are in linearity. For example, input signals 0-10V, the panel display 0-1000, the linear relationship: 0V displays 0, 5V displays 500, 10V displays 1000. If input is 4-20mA current signal, the LED panel displays 40-200, the linear relationship is 4mA displays 40, 12mA displays 120, 20mA displays 200. The max. display range is 9999, the min. display range is -1999.
SY LED6 LED Display meter has alarm function and 2-channel isolation switching quantity output, and can display, control, alarm output signal synchronously. That alarm function can be realized through programming. There are 2 wielding pad preset for user, if alarm function required, user needs to add 2 pieces of PC452 optical coupler. That LED meter has two alarm points, and positive, negative alarm direction setting. The alarm points is set based on the digits displayed in the LED panel, when it alarms, the last decimal point in LED panel is flashing, the alarm signal data output can drive the alarm unit of optical coupler. SY LED6 external shell is ABS plastic shell, external dimension is 72x36mm, height or thickness is 23mm.
