Loop Powered Voltage Signal to 4-20mA V/I Signal Converters

Features:
1. Unique high efficient signal loop power extraction technique, external power supply is not required. 
2. 2-wire V/I conversion, 3KVDC isolation between signal input and output. 
3. DC voltage signal input, loop powered 4-20mA output. 
4. Input potentio-meter signal: 0-2KΩ / 0-5KΩ / 0-10KΩ,etc. Input standard voltage signal: 0-5V/0 10V/1-5V/0-75mV,etc. 
5. Input terminal can provide distribution power (5V/3mA) regulated power supply for functions extension. 
6. High accuracy and linearity in full measuring range, non-linearity error grade <0.1%. 
7. Micro size (33X10.5X15.5mm), error grade: 0.1, 0.2. 
8. SIP7 Pin PCB-mounted, UL94V-0 flame-retardant package. 
9. Industrial operating temperature range: -40 ~ +85 oC.

Applications:
1. Displacement signal, potentiometer signal data acquisition isolation and control. 
2. PLC/DCS directly gathers voltage signals from sensor. 
3. Converts weighing mV signal into standard 4-20mA analog signal. 
4. Interference rejection of industrial field ground. 
5. Pressure signal acquisition and distribution 
6. Sensor voltage signal acquisition and long-term distortion-less transmission 
7. Bridge (weighing) detecting circuit voltage signal distribution and transmission
8. Voltage signal to passive 2-wire 4-20mA current signal isolated conversion: 1-input 1-output, 2 input 2-output, 3-input 3-output.
