GM0503D dosing controller instructions
I: Introduction
GM0503D series weighing controller uses the latest international technology development and production of ingredients for a new generation of instruments, static and dynamic measurement and intelligent instrument-specific ingredients. It combines the measurement and control functions into one, with constant scale, speed scale, supporting the use of static scales, to achieve a variety of materials weighing and batching. Instrument using a dedicated single-chip, all isolated analog input and output and digital input output interface, high-performance 20-bit A / D, 10 bit D / A converter, together with the RS-485 communication interface, easy access to the DCS system . Intelligent PI output of the inverter, motor controllers slip actuator for closed loop control, GM0503D for LCD character display.
II: system function
1: special industrial control microprocessors, super anti-static, anti-interference, to ensure that the system is stable and reliable.
2: EEROM protection parameters, and output data can be stored for more than ten years is not lost.
3: low temperature drift, low noise amplifier chip to ensure signal stability.
4: Road analog inputs, three analog outputs. Analog Input: 131 072 number.
Analog Output: Road 0 ~ 5V, 4 ~ 20mA output way.
5: The instrument has run the auto-zero, the alarm automatically delayed shutdown feature.
6: metering accuracy: better than 0.05 ‰
7: Four-row LCD character display parameters, 21 working keys, five LED status lights.
8: Optional control two kinds of scale body: constant speed weighing scale.
9: speed pulse input (optional for the speed sensor to provide 12V power supply).
11: choice of local, remote and 485 controls start, stop.
12:0 ~ 10mA, 0 ~ 20mA or 4 ~ 20mA external setting input.
13:0 ~ 10mA, 0 ~ 20mA or 4 ~ 20mA output current flow.
14: All digital input and output full optical isolation.
15: sensor supply 5V, current 150 mA.
16: Relay output: running, ready, alarm, limit alarm, lower limit alarm, and tons of cumulative production.
17: Instrument with two zoom functions: a hardware zoom, two program-controlled amplification.
18: RS-485 communication interface, using MODBUS communication protocol for easy networking with PLC and other devices.
19: the host CPU, AD, DA power independent of each other, to ensure that input and output and do not interfere.
