Introduction:
SunYuan ISO EC series analog signal isolation amplifier is a capacitive coupling isolation hybrid integrated circuit with strong EMC immunity. The amplifier adopts a brand-new modulation-demodulation capacitive coupling isolation technology. The signal in the module is transmitted as a digital signal through a capacitive isolation layer. The integrity of the signal is maintained by digital modulation and capacitive coupling isolation, so that the digital signal can also provide excellent reliability and superior high frequency transient immunity through the capacitive isolation layer.
ISO EC series modules adopt small size standard SIP12Pin flame retardant shell and resin material packaging mode, adopt single power supply and integrate a group of isolated DC/DC conversion power supply and a group of capacitive coupling analog signal isolation amplifier on the same chip. The module supports analog single-ended input to positive and negative signals and positive and negative signals to single-ended signals isolation transmission function, no external potentiometer and other components, free of zero and gain adjustment, which greatly simplifies the user's design and field use costs. Capacitive isolation technology is used inside the product, which has better EMC interference resistance than magnetoelectric isolation technology, and better temperature drift characteristics and linearity than optocoupler isolation technology, eliminating the need to repeatedly calibrate zero and full degree. Auxiliary power supply single power supply and signal input, output between the 3000VDC three isolation design, so that users at the same time in the use of multi-channel modules, can use a single or multiple power supply.
ISO EC series modules are simple and easy to use, the products have two installation methods: PCB board welding and standard DIN 35 rail card slot fixing, the guide rail installation can realize the isolation, distribution, amplification and conversion functions of various sensors and instrumentation or control system signals in industrial sites such as one in and two out, one in and three out, two in and two out, etc., and can meet the requirements of humidity, vibration and wide temperature range (-40 ~ +85 °C) of industrial use environment. It is widely used in rail voltage monitoring, generator or motor safety operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal transmission and reception, medical equipment safety isolation barrier, industrial robot automation control, chemical and nuclear power equipment and other fields.
