Non-isolation 4-20mA, 9V - 15V Differential Signal Acquisition Converter for PLC / DCS Data
Certification:ISO9001-2008, CE, RoHS
Non-isolation 4-20mA, ± 9V - ± 15V Differential Signal Acquisition Converter for PLC / DCS Data
The IC contains an internal differential signal acquisition, conditioning and conversion circuits coupled. Standard input equivalent resistance, so that the IC can be collected from the sensor circuit, differential signal, in order to meet the user\'s MCU receives the signal needs. (± 9 ~ ± 15V) Wide range power supply or single power supply. Output is 24VDC and sampling resistance (load resistance) wire in series to power supply circuit design, with the current commonly used analog input interface board (PC), PLC, DCS, and other commonly used instruments of the analog input port match. And can meet the temperature, humidity, vibration and other industrial site in harsh environment. SY C-A-P-O is easy to use, do not take any regulation loop that can achieve the required accuracy, to achieve the two-wire 4-20mA signal transmission and transmitter functions.
Applications:
>>PLC/DCS data acquisition
>>Differential 4-20mA signal acquisition Conditioning and transmission
>>Sensor signal and analog input interface to match
>>Signal transmit no-distortion
>>Signal transceiver and control instruments
>>Industrial analog signal data acquisition and control
Specifications:
>>Two wires differential signal input, common ground output
>>(±9~±15V) wide range power supply or single power supply
