The D8000 series USB interface modules are a family of complete data acquisition modules for use in process control systems. The analog input models can measure process signals such as thermocouples, 4 to 20 mA current loops, and discrete contact closures. The analog output models can generate voltage or current signals for controlling annunciators or valves. The digital input and output models can sense the state of remote digital signals or control solid state relays. Complete data acquisition systems can be created with ease with the D8000 modules and a host computer.
The modules provide direct connection to a wide variety of sensors and annunciators such as thermocouple probes, 4 to 20 mA loops, and DC voltage. They perform all signal conditioning, linearisation and contain no internal pots or DIP switches. All user-selectable features such as ranges, communications settings are stored in non-volatile EEPROM, which maintains these values even after power is removed.
The D8000 series USB interface modules connect to a host computer using a USB interface cable and they communicate using a virtual serial communications port using the Modbus RTU protocol.
Use a USB cable to connect the D8000 to a host computer. Plugging the cable into the computer will create a virtual serial port in the computer. The virtual serial port will be used by the host to communicate with the module. Serial communication ports are supported by almost all data acquisition and process control programs in the marketplace.
The Modbus RTU protocol is used to read and write data values to the D8000 series modules. The Modbus RTU protocol is a serial protocol and communicates with external devices through serial ports. The Modbus RTU protocol is widely recognized throughout the data acquisition industry and is supported by almost all commercial process control programs.
Multiple D8000 series modules can be connected to one host computer. A unique and separate serial port is created for each module that is connected. The serial port approach provides instant compatibility with almost all industry standard data acquisition programs that support the Modbus RTU protocol.
With the D8000 series modules, anyone familiar with a personal computer can construct a data acquisition system. This approach to data acquisition is very flexible, easy to use and cost effective. The modules can be mixed and matched to fit your application. You do not need engineering experience in complicated data acquisition hardware to build a system.
