XK3101 + type profibus-DP bus weighing control instrument
XK3101 + is for industrial control in the field of electronic weighing instruments, with a variety of serial communication interface protocol ( the Modbus and the Profibus ), digital input and output interfaces, scalable Analog interface, digital outputs can be configured in four ways, you can use in the ingredients, value addition, the lower limit detection and other occasions; rich communication interface directly with the DCS connection system. Cabinet-mounted instruments using aluminum alloy shell, can be easily embedded in the control cabinet.
Dimensions shown below.
The need to install the cabinet panel cutout, dimensions: 101mm × 191 mm , the depth of the control cabinet must not be less than 250mm .
The main features of the instrument
※ Using seven VFD (Vacuum Fluorescent Display);
※ standard isolation RS232 / RS485 communication interface;
※ standard 10-way (optically coupled isolator) switch (4 inputs 6-channel transistor open collector output);
※ Key lock function
※ Scalable Profibus interface (optional);
※ scalable 4-20mA / 0-10V analog output interface (optional, precision 0.2% FS);
※ built-in auxiliary DC12V / 300mA power output (relay output can drive);
※ Switching output settings – batching mode (double speed double, single speed 4 material), and the upper and lower limit setting mode mode;
Technical Parameters
1 analog portion
Sensor excitation: DC 5V, current is not less than 120mA
( Drive eight 350 ohm load cells)
ADC conversion speed: 7.5 / 15/25 / 50Hz
Analog signal input range: 0 ~ ± 10mV
Input signal sensitivity: ≥1.5uV / e
Dividing the value range 1,2,5 :() × 10 K , K = (- 3, -2, -1,0,1)
2 external input-output
External 4-way isolation, input, zero , tare , clear (tare and alarm signal) and start / stop function.
External Output: 6-way open collector outputs, including four preset output, error indication and operation / stop indication. The maximum sink current output circuit is 50mA , external drive voltage can not exceed DC30V .
In addition, the instrument also provides a set of independent DC 12V / 300mA power supply can be used to drive an external relay.
3 serial communication interface
Standard isolation RS232 and RS485 interface, supports two communication protocols: continuous send or command mode. Command mode supports MODBUS protocol (RTU mode)
You can set the communication parameters: baud rate, frame format, etc.
4 Profibus interface (optional code XK3101 + -OP2)
It supports complete PROFIBUS-DP protocol;
Bus maximum transfer rate of 12Mbit / s, adaptive baud rate;
It supports both synchronous and freeze mode;
5 analog output module (optional code XK3101 + -OP1)
The analog output module includes a 0-10V voltage output and 4-20mA current output, but not both simultaneously. Output voltage is not less than the requirements of the load resistance of 100k [Omega] , the current output load resistance of less than 500 [Omega].
6 environmental conditions
Power: AC 220V + 10% -15%; Frequency: 49 ~ 51Hz
Power consumption: ≦ 20 watts
Environment: Temperature 0 ℃ ~ 40 ℃; Humidity: 10 ~ 85% RH;
Storage environment: Temperature 0 ℃ ~ 50 ℃; Humidity: 10 ~ 85% RH;
Instruments need good ground , and not with motors, AC contactors, heaters and other equipment is easy to produce a common power supply noise of a power supply !
