PWM.Processing control and automatic equipmentPWM to 2-wire 4-20mA
signal isolated control,1-channel input 1-channel output or 2-in
2-out isolated conversion.Description :SunYuan ISO D-O1 is an
micro-size low power consumption passive integrated transmitter IC
designedfor the isolated conversion from PWM pulse width signal
into 2-wire 4-20mA signal. 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.General Parameters :Accuracy,linearity error
