SYS Non-Isolated Analog Signal Amplifier and Converter IC

Sunyuan SYS U-P-O series analog voltage signal and SYS A-P-O series analog current signal amplifier and transmitter IC, using a small volume (single row of four pins, SIP4 Pin) low-cost design scheme, is mainly used to solve the sensor and instrumentation, PLC, DCS interface to match the interface between: 0-2.5V/0-5V/1-5V/0-10V/0-20mA/4-20mA and other standard analog signals and non-standard conversion problems. 20mA/4-20mA and other standard analog and non-standard analog signal conversion problems. The product has ultra-high precision (0.05% error in full scale) and high linearity (0.1% error in full scale), the design adopts the common ground between the working power supply and the signal channel, without the need for external adjusting potentiometer and other components, free of zero and gain adjustment of the simplified program, applicable to the field instrumentation in the zero bias of the analog signal conversion and amplification (eg: 1-5V and 0-5V, 4-20mA) With 0-10V and other input signal zero bias, and the output signal zero need to set the value of "0" applications), can realize the industrial field instrumentation interface between the analog signal matching, conversion and remote amplification functions.

        SYS U-P-O series and SYS A-P-O series products adopt advanced feedback zeroing technology, which can ensure the high accuracy of zero point and fullness value within the range of signal input and output. Due to the size limitation, the internal power supply of the product is not boosted and isolated, so the power supply voltage must be higher than the signal output voltage by more than 2VDC. (For example, if the output signal is 0-5V, the power supply voltage should be more than 7VDC, and 9VDC or 12VDC is optional). Users who need full isolation of signal and power supply should use our ISO EM U-P-O or ISO EM A-P-O series products.

         SYS U-P-O series and SYS A-P-O series products are mainly used for direct high-precision conversion and amplification of analog voltage and current signals without isolation. Compared with ISO series photoelectric isolation amplifiers and ISO EM series magnetic isolation transmitters, they have smaller volume, lower cost and better accuracy and linearity. Widely used in metallurgy and mining, petrochemical industry, electric power equipment, medical instruments, industrial automation, new energy facilities and military scientific research and other fields, the user can choose the appropriate products according to the needs of the site.
