ISO EC Dual-Channel 3kVDC Analog Signal Isolation Amplifier

 ISO EC series dual-channel analog signal isolation amplifier is the industry's first with strong resistance to EMC interference characteristics of the set of capacitively coupled isolation amplification, conversion and distribution of three-in-one hybrid integrated module (invention patent application No.: 2025109476011). Adopting the new modulation-demodulation capacitive coupling isolation technology of SunYuan Technology.Sensor analog signals for analog-to-digital modulation to digital signals through the capacitive isolation layer for isolation and transmission, and then by the digital-to-analog conversion circuit to restore the analog signal output, digital modulation and capacitive coupling isolation to maintain the integrity of the signal, and the signal through the capacitive isolation layer can also provide excellent reliability and superior immunity to high-frequency transients.The product is designed for the space interference EMC electromagnetic compatibility characteristics and high precision, high security two-way analog signal isolation and amplification conversion distribution of industrial scenarios.Internal 3000VDC six isolation technology with wide creepage distance is adopted to realize complete electrical isolation between signal input, output, working power supply and each signal channel.It suitable for eliminating ground loop interference, common mode noise suppression, isolation of high-voltage impact and other harsh environments, to ensure the reliability of signal transmission and the safety of equipment operation, industrial automation, instrumentation and sensors and other industries to solve the problem of on-site EMC electromagnetic compatibility of the signal transmission of the ideal solution.

   ISO EC series analog signal isolation amplifier adopts the integrated design of dual signal transmission channels, which reduces the field installation cost and space occupation directly, 2-inpuut&2-output channels are isolated independently, and the two signals are transmitted in parallel.Avoid crosstalk between signal channels, with signal 1-input&2-output, 2-input&2-output isolation amplification, conversion and distribution of three-in-one function, effectively reducing the complexity of the system and cost reduction.At the same time to support dual-channel different analog signals independent and flexible matching, dual-channel input and output signal types can be selected from the same or different types of free combinations, to facilitate the user according to the requirements of the site to match.

   ISO EC Series Analog Signal Isolation Amplifier Modules are housed in small, standard SIP 16Pin (16-pin single in-line) flame retardant housings and resin packages.A set of single-supply-powered multiple isolated DC/DC converter circuits and multiple capacitively coupled signal isolators are integrated internally.Support analog single-ended input to positive and negative signals and positive and negative signals to single-ended signal isolation and transmission function, the whole without external potentiometer and other electronic components, free of zero and gain adjustment, thus greatly simplifying the user's system design and field use of cost.The internal analog signal transmission adopts capacitive coupling isolation technology, which has superior anti-EMC interference capability compared with magnetic isolation, and better temperature-drift characteristics and linearity compared with optoelectronic isolation technology, and omits the tedious work of repeatedly calibrating zero and fullness when in use.The auxiliary power supply adopts a single power supply and 3KVDC six-isolation design with signal input, output and channel, which enables users to use single or multiple power supply when using multiple modules at the same time, and effectively reduces the design cost and volume of the control system.

   The ISO EC series modules are easy to use and are available in module packages for soldering on PCBs or for mounting in standard DIN 35 rail mounting slots. Both installation modes can realize 1-input&2-output, 2-input&2-output and other industrial field of various sensors, transmitters and instrumentation or control system letter analog signal isolation distribution, amplification and conversion function, and can meet the humidity, vibration and a wide range of temperatures (-40 ~ +85 ℃) of the industrial-grade use of environmental requirements.The products are specially designed for the complex industrial field environment, which can eliminate ground loop tampering, isolate high-voltage impact, convert signal types, signal amplification and long-wire distortion-free transmission and so on. They are widely used in the fields of rail voltage monitoring, generator or motor safety operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal sending and receiving, medical equipment and new energy systems, industrial robot automation control, chemical and nuclear power equipment, and so on.
