Introduction:
Sunyuan ISO V-4-20mA is kind of SIP 12Pin PCB-mounted passive 2-wire voltage to 4-20mA isolation transmitters. The isolation transmitter IC can provide a set of 5V(3mA) power supply for function extension in next step current loop powered mode. And it receives the voltage signal from the input terminal and converts it into standard 4-20mA 2-wire current signal.
The design of product follows the low cost, small size standards, and adopts SIP12PIN fire protection IC package. Inside the product, there are current signal modulation circuit, magneto-electric isolation transform circuit and signal reduction demodulation circuit. It’s power supply voltage range is 12-36VDC, low input equivalent resistance, high linearity, the isolation withstand voltage between signal input and output is up to 3000VDC. The power modules are convenient to use, which achieve isolated distribution of voltage signals from the two-wire voltage input distribution sensor and bridge (weighing) detection circuit only by adding some peripheral devices. The isolation transmitter can be used with sensor to directly convert displacement, angle resistance signal into standard 4-20mA signal, zero and gain can be adjusted by adding external potentiometers. When using the module, user should refer to the typical application circuit diagram.
Unique magneto-electric isolation mode and high efficient loop powered technology are used to make the modules convert voltage signal into standard 2-wire 4-20mA signal. The signal transmitter is compatible with the standard analog input terminals, like PLC, DCS, Digital display meter. It can be used in normal in abominable industrial conditions like wide temperature, humidity and vibration. The signal transmitter have two types of package, small size PCB-mounted package, 35mm DIN rail-mounted package. The 35mm DIN rail-mounted products can be 1-input 1-output, 2-input 2-output, 3-input 3-output and 16-channel V/I isolated conversion functions.
