Description
DIN 1X1 ISO 4-20mA (LED) Current Loop Signal Intelligent LED Digital Meter adopts low power consumption
current loop circuits and electricity stealing technology, which has the following functions: display, alarm, isolated transmission.
The product consists of current signal modulation and demodulation circuits, signal coupling isolated conversion circuits,
display and alarm controlling circuits. The small input equivalent resistance used achieves the ultra wide voltage input range (12
~ 36VDC) which meets the users’ various requirements in signal isolation, display, alarm, long-distance transmission without
distortion in passive mode. Internal integration and new isolation technologies enable the device to reach 3KDC insulation
voltage and meet industrial grade temperature, humidity, shake harsh environmental requirements. DIN1X1 ISO 4-20mA (LED)
series are easy to use, standard DIN35 rail mounting design, convenient for users to install and use. The products can achieve
4-20mA current loop signal isolation, display and control functions without external power supply and other components.
DIN 1X1 ISO 4-20mA (LED) has a variety of functions which are different from that of the traditional products by adopting
intelligent design. It is a kind of passive products which can transmit and isolate the 4-20mA signal in the current loop, and
display it correspondingly in decimal figures based on the set range. Two-wire passive operating mode, without external power
supply, so it is easy to do wiring and has small size, high precision, low cost. Traditional digital meter adopts potentiometer
adjustment technology, it is not flexible in adjustment and easy to be influenced by temperature. That intelligent digital meter
has two adjusting buttons, which controlled by the central processor CPU, can be used to set zero, span, a decimal point, alarm,
time delay and other parameters, so it has strong flexibility in application. The digital panel meter adopts LED display panel,
constant current drive, it has good performance in display and has anti-reverse, over-current protection function. The digital
meter is widely used in industry control, petroleum chemical industry, environmental protection, intelligent home furnishing,
mining and other controlling devices on temperature, pressure, flow, liquid level, etc
