Introduction:

ISO U-O(voltage signal), ISO A-O(current signal), series are the smallest size low cost passive loop powered analog signal isolation amplifier IC modules. Unique high efficiency loop powered technology has been applied in design the module which enable it works without external power supply. It is powered by the back loop powered output. The IC module can be applied in various types of analog signal input: 2-wire, 3-wire, 4-wire sensor active signals to 4~20mA, 2-10mA, 4-12mA. 4-8mA, 12-20mA,etc 2-wire analog current signals amplification and isolation.

The design of product follows the low cost, small size standards, and adopts SIP12PIN flame-retardant IC package. Inside the product, there are current signal modulation circuit, magneto-electric isolation transform circuit and signal reduction demodulation circuit. Low input equivalent resistance, high linearity. The power modules are convenient to use, which achieve isolated distribution from meters, sensor, transmitter, resistance potentiometers signal to standard 2-wire 4-20ma current loop signal only by adding some peripheral components. Zero and gain can be adjusted by adding external potentiometers. Its isolation withstand voltage between signal input and output is up to 3000VDC and can meet the requirements that operating in industrial field wide temperature, humidity, vibration, etc adverse operation conditions. Loop powered voltage is 15-30V dc voltage, the recommended voltage range is 10% of the rated voltage value.

Unique magneto-electric isolation mode and high efficient loop powered technology are used to make the modules convert dc voltage, current, potentiometer, resistance signal into standard 2-wire 4-20mA loop powered current signal. The signal transmitter is compatible with the standard analog input terminals, like PLC, DCS, and Digital display meter. It can be used in normal in abominable industrial conditions like wide temperature, humidity and vibration. The signal transmitter has two types of package, small size PCB-mounted package and 35mm DIN rail-mounted package. The 35mm DIN rail-mounted products support 1-input 1-output, 1-input 2-outputs, 1-input 3-output, 2-input 2-output, 3-input 3-output and 8-channel,16-channel V/I isolated conversion functions.
