That IC operates in currentloop powered in output terminal mode, it receives PMM signal from input, and converts it into correspondingisolated 4-20mA standard 2-wire current signal in linearity.SunYuan ISO D-O1 series PWM Pulse width transmitter is a kind of integrated mixed circuits which canconvert the duty ratio of PWM signal into isolated standard current signal. The transmitter IC is in low cost, smallsize standard SIP 8Pin flame-retardant package. It has combined with the following circuits: signal coupling isolated conversion circuit, precision reference voltage source switching control circuit, low-pass filtering circuit, driving amplification circuit, VI conversion circuit, etc. The output loop powered power supply range is 12-36VDC, PWM signal is converted in high accuracy and linearity. The hybrid integrated circuit and isolated technique used enable that transmitter IC to operate in 3KV isolation between input and output and operate normally in the severe operating environment, like high/low temperature, humidity, shake, etc in industrial site.SunYuan ISO D-O1 is designed by using high speed optically coupled isolation mode and high efficiencyfeedback loop powered technique to achieve the isolated conversion from PWM signal to 4-20mA standard signal. It can be well matched with the input interface of various types of meters and instruments like PLC, DCS, FCS, etc. Operating in loop powered mode and extra small size (22.0X11.0X9.0mm) can effectively simplify user's system layout and save the space and cost in designing an application solution. The transmitter has 35mm DIN Rail-mounting package and PIM embedded board with display type. For 35mm rail-mounting type, it has single input, single output, dual input-output, triple input-output type. PIM embedded board with display type can realize sensor signal isolation and display, alarm control, long-distance transmission without distortion. It is widely applied to electric power system, telecom, instrumentations & measurements, medical equipments, industrial intelligent control, automotive electronics, security-monitoring system, military industry, etc. General Parameters :Accuracy,linearity error grade--------------0.1,0.2,0.5Load regulation------------Auxiliary power supply -----NoneIsolation----Dual isolation between input and outputOperating temperature--- -40 -+85degreepackage-------SIP 8pinOperating humidity-----10-90%(non-condensationwithstand voltage-----3KV(60HZ/S),leakage current
