The A/D weighing module is connected via Modbus/RS485 protocol

Description :

　　The A/D weighing module is a measurement module specifically designed for the weighing industry. This module has built-in functions such as filters, power on zeroing, zero tracking, tare weight setting, and tare removal. All components inside the module use industrial grade chips, which can operate within -40 ° C; Up to 85&# 176; The range works normally and adopts a low-temperature drift circuit design, with a temperature drift of only 3ppm/; C， More adaptable to various demanding application environments. The module adopts half duplex RS-485 and RS232 communication, and users can easily convert the 232 interface to other communication methods (such as 422 communication) through accessories, and connect to the main control device using Modbus industrial communication protocol. In addition, the module is equipped with PC debugging tools for users to easily set parameters. Chapter 2 Characteristics and Indicators The main features of the AD module are:? Working voltage 17-24V DC, built-in anti reverse circuit, built-in recoverable fuse, maximum allowable current of 0.3A;? RS-485 or RS-232 serial port transmission (only one communication method can be selected for each communication);? Using Modbus protocol, supporting RTU and ASCII modes;? Support device address encoding: 1-32 addresses;? Measurement signal large range:+10mV~+5V;? Baud rate: 9600 bps, 19200 bps (default), 57600 bps;? Hardware configuration with factory reset, which can restore factory settings. As shown in Figure 1, short circuit is sufficient. (Factory default communication parameters: baud rate 19200, even parity, one stop bit, 8-bit data bits, device address 1, RTU communication mode);? Working current (AD module only): approximately 35-65mA (depending on the processor's computational complexity, the sampling rate determines the computational complexity);? Operating temperature range: -40 ℃ to+85 ℃;? Storage temperature range: -60 ℃ to+90 ℃;? AD module bare board size (mm): 60&# 215; 60× 1.6 (length, width, height);? AD module plastic shell size (mm): 65&# 215; 62× 24 (length, width, height);? Weight: Approximately 76g. If you need more information, please contact: Contact: He Shiping Website:
