DescriptionBRTHX750 Electric scale signal converter module is a load cell sensor signal ad conversion module. It is designed to convert the changes/movements into resistance value and outputs digital signal after processing through precision conversion circuit. That load cell AD converter module supports PC communication through TTL-RS232 converter. It has eight pins for PCB installation and further development, very convenient to use.Features & Benefits ● 24bit high accuracy AD conversion chip. ● 80Hz frequency refresh. ● /-20mV signal input, 5V operating power supply. ● Simple integrated circuit design with 8 pins. ● High reliable, high sensitivity and efficient output. ● Fast speed measurement. ● Support communication with PC via TTL ports, set via software.Typical Applications ● Measure pressure, force, displacement, strain, etc. ● Measure torque, acceleration, etc. ● Electric scale sensor signal conversion. ● HX711 ADC weighing signal data acquisition.Technical ParametersTermsTYP ValueNoteDifferential voltage input /-20mVFull scale differential input voltage /-40mVData accuracy24 bit24 bit A/D Conversion chipRefresh frequency80HzRefresh data frequencyOperating power supply5VDCOperating current<10mAOutput PortsTTLNeed TTL to RS232 converterCommunication ProtocolHEX CharacterSet via SoftwareBaud rate9600bpsNo check bit, 8-byte data, 1 byte stop.DataComplement of two’sOperating temperature-10 to 50℃Storage temperature-40 to 65℃Size38x22x10mmLxWxHInstallation & Wiring CircuitLoad cell signal converter circuitPin DescriptionPin Code NoDescriptionP2 Pin terminals5V5V operating power supply GND5V operating power supply –RXDReceiving pin, connect to MCU TXDTXDTransmitting pin, connect to MCU RXDCH1 Pin terminalsVDDElectric scale power supply (red wire)I Electric scale same phase input (green wire)I-Electric scale reverse phase input (white wire)GNDElectric scale power supply -(black wire)*Please do not connect the AD Converter module to serial port of PC directly, it needs a RS232 to TTL converter to do signal conversion, then connect the AD converter module to the PC through RS232 to TTL converter, otherwise, it may cause damage to the electric scale AD module. (RS232 signal is from -15V to 15V, TTL-232 signal is from 0V to 5V.)
