1.1 Overview
YR-2180 weighing A/D module, an independently developed industrial grade digital weighing A/D conversion module. Digital calibration, peeling, zeroing, zero point tracking, serial communication, etc.)
Improved hardware design and enhanced dynamic digital filtering function make the product more comprehensive and reliable, especially suitable for various industrial dynamic weighing occasions.
1.2 Performance indicators
A/D resolution
24 bit (AD chip HX710B)
A/D acquisition rate
10 times/second, or 40 times/second, (default to 10)
digital filter
Flexible setting, fast convergence and stability of weighing data, calibration, peeling, zeroing, zero tracking, etc
Static weighing accuracy
Sensor range 0-20kg, Max set to 3 decimal points, MAX display 20.000Kg
Sensor range 11-200kg Sensor, set to 2 decimal points for Most, MAX displays 200.00kg
Sensor range 201-2000kg Sensor, set to 1 decimal point for Most, MAX displays 2000.0kg
The sensor has a range of over 2000kg and cannot set a decimal point,
If four 200kg sensors are used, the total range is calculated at 800kg, and the decimal point is set to 1)
communication interface
New original (TI Texas Instruments Industrial Grade) 485 chip, model: SN65HVD3082EDR
Support TTL interface or RS485 interface, standard Modbus RTU communication protocol, measured value support long shaping data/floating point
Baud rate
1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 optional (default 9600, no verification)
Number of sensors
When powered by 5V TTL serial port: MAX can connect 1-4 350Q weighing sensors
When powered by 9V, the MAX can be connected to one 350Q weighing sensor (when powered by 9V, the temperature of the 78L05 power chip is about 25 "C)
When powered by 12V, the MAX can be connected to one 350Q weighing sensor (when powered by 12V, the temperature of the 78L05 power chip is about 30'C)
When powered by 24V: MAX can connect 1 to 1 350Q weighing sensor (when powered by 24V, the temperature of the 78L05 power chip is about 50 ° C)
Kind reminder: It is recommended to use 9V or 12V power supply, with optimal results
Power heating issue: Considering that this module is sensitive to the power supply, LDO is chosen as the power circuit to ensure the purity of the power supply.
External power supply
Support 5V-TL power supply or DC9-24V power supply. It is recommended to use DC9V or DC12V power supply.
Number of sensors
When powered by TTL-5V, 2-4 sensors can be connected. When powered by 12V, only one sensor can be connected.
