Give coal machine controller belt scale accumulator MTZD6000

 1.1 Introduction MTZD6000 belt scale control instrument is a kind of high performance control instrument specially designed for belt scale. The instrument adopts industrial components design, LCD display, surface mount technology production, a variety of anti-interference measures and a number of new achievements of single chip microcomputer, with powerful functions, small size, high reliability and strong adaptability. The MTZD6000 instrument operates in both speed-adjustable and constant-speed modes, designed for controlling belt scales of various configurations and measurement ranges. It also supports dynamic weighing systems including screw scales, disc scales, and rotor scales. By integrating cutting-edge technologies, this instrument demonstrates exceptional advantages in product reliability, operational flexibility, and user-friendly operation. 1.2 Function features 1. Standard RS-485 communication function, following the standard MODBUS protocol, fast communication speed and high reliability. (Optional function) 2. The operation interface is a full Chinese LCD display, and the operation mode of digital keys makes the operation more simple and intuitive. It has the language selection function, which can switch between Chinese and English display. 3. The instrument can be operated through the keyboard, external signal (port) and host computer. 4. Four calibration methods, optional chain code calibration, physical calibration, dynamic hanging code calibration and static calibration, are available to meet the needs of different users. 5. It can be connected to the host computer, PLC or DCS through different interfaces. 6. The standby or running status can display 8 parameters on 3 screens. 7. It has two working modes: speed regulation (pulse speed measurement and voltage speed measurement) and constant speed. 8. All parameters are set with upper and lower limits and default values, which are set according to the default values when leaving the factory. 9. The "Flow setting mode" of the instrument can be switched to three ways: "external interface", "instrument keyboard" or "communication" through parameter setting. 10. It has a cumulative pulse output, and the pulse width and equivalent (the amount of material represented by each pulse) can be set through parameters. 11. The gain of the analog input channel can be modified according to the input voltage range. 12. It has the function of parameter backup and recovery, and can directly restore to the state before the fault when the instrument is abnormal. 13. Coefficient correction function: real-time adjustment can be made without recalibration after the occurrence of flow and cumulative errors. 14. The "initial DA" value changes with the value of the "set flow rate" parameter. If the set flow rate is 0, the "initial DA" value is not calculated. 1.3 Technical parameters 1. Working power supply: 85-265VAC/10W. 2. Working environment: -10-50℃/10-95%RH (no condensation). 3. Opening size: 75 (H)*151 (W) (unit: mm). 4. Weight detection: The resolution is 16 bits, the input sensitivity is 0.2-1.0μV/d (according to the gain set by the factory), and the error is less than 0.01%. 5. Speed measurement: error less than 0.01%, pulse frequency range 1-3000Hz. The instrument provides the working power supply of the speed sensor 16V/30mA. 6. Comprehensive error of instrument: less than 0.02%. 7. Display bits: 5 bits (except the cumulative value). 8. Analog input channel: 16-bit, 2CH, adjustable gain. CH1 can be directly connected to the weighing sensor, and the instrument provides the sensor with a power supply of 10V/200mA; CH2 The input signal is 0-20mA or 4-20mA current signal. 9. Analog output channel: 12-bit, 2CH. Dual current output: CH1 and CH2 are 4-20mA output (upper and lower limits can be set), the load is less than 500 ohms. 10. Switching output channel: 8 channels in OC form, which can drive 200mA/50V DC resistance load. 11. Switching input channels: 8 channels, pull-down effective (short to ground). Drive capacity is 10mA.
