商品説明The D6000 Series 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 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 D6000 modules and a host supervisory computer or programmable logic controller. 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, communications settings are stored in nonvolatile EEPROM, which maintains these values even after power is removed. The D6000 series modules communicate with a host computer using the MODBUS RTU protocol. The MODBUS RTU protocol is widely recognized throughout the data acquisition industry by and supported by almost all commercially available process control programs and supervisory host PLC’s.
