Introduction:

Sunyuan ISOS 4-20mA-F micro-size, low cost high precision SIP 7pin two-wire passive loop powered isolated distributor IC is a kind of signal magneto-electric hybrid integrated circuits. The signal distributor can supply power to the 2-wire passive sensor or PLC, DCS equipment in loop powered method, and it can receive the 4-20mA signal from 2-wire sensor or other meters and instruments at the same time, then outputs the 4-20mA in the same linearity and ratio. Inside the ISOS 4-20mA-F module, there are signal interference suppression circuit, signal modulation circuit, signal isolation circuit and output demodulation filtering circuit. DC-DC step-up circuit provides 16V-21.5VDC distribution power supply to the 2-wire sensors or PLC, DCS, that function simplify the procedures in signal measuring, transmission and isolation of 2-wire sensors and meets the customer requirements in long-distance transmission without distortion. The isolated distributor is designed on the basis of two wire loop powered (explosion-proof) circuit which has serial connection on 24VDC and sample resistance (load resistance). It can be well matched with analog input interface board (host machine), PLC, DCS and other meters and instruments with analog input interfaces. Internal isolation technique, integration technique are used to realize that the isolated voltage is up to 3000VDC, and the distributor can meet the industrial operating temperature range, humidity, vibration and other harsh environment requirements.

ISOS 4-20MA-F Two-wire 4-20mA loop powered distributor is easy to achieve two-wire sensor signal isolation, transmission and power distribution without external components and auxiliary power supply. The unique magneto-electric isolation mode and high efficiency loop powered technique used provides solution of the power supply in sensor or transmitter 4-20mA signal isolation and transmission in high accuracy. The signal conditioner has 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 isolation, etc.
