Computerized Data Acquisition System
Ⅰ. PC + PCI
Application:
Suitable for high speed acquisition and control, does catch the real test process.
Adequate for the equipment used in labs, mass data acquisition/storage and historical data query, etc.
Technical Data:
Switching value single point rating current：1A/24VDC
Input signal：0 ~ 10V, 0 ~ 5V, 0 ~ 2.5V, 0 ~ 1.25V
Output signal：0 ~ 5V
Acquisition channels：16 (Max)
Sampling frequency：≥1000Hz
Sampling accuracy：0.5%FS
Features:
The PC, with powerful data processing capacity and superior performance, is used to process all kinds of communication commands, including data gathering, storaging/displaying, graphic displaying, test report generating and printing, etc.
PCI-1716L card is inserted into the PC directly, and the use of bus data transmission, the communication-time between PCI&PC can be simply ignored, greatly improved sampling and control rate.
The PCI-1761 relay actuator and isolated DI card is an add-on card for the PCI bus. 8 relay output channels and 8 isolated digital input channels, isolation protection of 2,500 VDC for collecting digital inputs in noisy environments. Directly control the solenoid valves.
Ⅱ. PC + PLC
Application:
This data acquisition system is most appropriate for lab, mass data acquisition/storage and historical data query, etc.
Technical Data:
Power supply：20.4 ～28.8VDC
Switching value single point rating current：0.75A/24VDC
Analog input：0～10V, 0～5V, 0～1V, 0～500mV, 0～100mV, 0～50mV, 0～20mA
Analog output：0～10V, 0～20mA
Sampling frequency: 20Hz, Controlled resolution：±2%FS or ＞0.2MPa
Features:
The PC, with powerful data processing capacity and superior performance, is used to process all kinds of communication commands, including data gathering, storaging/displaying, graphic displaying, test report generating and printing, etc.
Siemens PLC applied to all kinds of occasions of detection, monitor and automation&control.
Ⅲ. Touch Screen + PLC
Application:
Most appropriate for site operation or production line operation, small amounts of data acquisition/storage and, simple human-computer interfaces which have no use for the functions of graphics displaying, printing, and historical data querying.
Technical Data:
Sampling frequency: 1Hz（graphic displaying）or 20Hz（digit display）
Controlled resolution：±2%FS or ＞0.2MPa
Features:
Adopt eview touch screen controller. Compact and lightweight, flexible operation. Properly handling the various communication commands, including data acquisition/storage, digital/graphic display, etc.
Siemens PLC applied to all kinds of occasions of detection, monitor and automation&control.
