D8000 Series USB Data Acquisition Modules 00580

The D8000 USB Data Acquisition modules are a complete family of data acquisition modules for use in process control systems. These modules can measure process signals such as thermocouples, 4-20mA loops, discrete contact closures, and they can generate voltage or current signals for controlling annunciators or valves. Complete data acquisition systems can be created with ease with the D8000 modules and a host supervisory computer.

The modules provide direct connection to a wide variety of sensors and annunciators. They perform all signal conditioning and linearization and contain no pots or DIP switches. All user-selectable settings, such as ranges are stored in nonvolatile EEPROM, which maintains these values even after power is removed.

The D8000 series remote I/O modules are compatible with all commercial  software programs and OPC servers that support the Modbus RTU protocol. Commercials software programs from DreamReport, Wonderware,  National Instruments Labview, Indusoft, DAQFactory and  DASYLab all support the Modbus RTU protocol. OPC Servers from  Kepware and MatrikonOPC support the Modbus RTU protocol.
