The D5300 thermocouple input module is part of the DGH’s D5000 low cost multichannel data acquisition module family. This input module supports up to four channels and converts the thermocouple analog input signal to digital data at the rate of 8 conversions per second, then converts the data to engineering units using the lookup tables, storing the latest data in the buffer. Four thermocouple types are supported – J, K, T and E (factory set). The data can be retrieved by sending an ASCII command from the host computer. For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings, meaning the values are maintained in the event of power loss. The D5300 comes pre-set with default values of 300 baud, one start bit, eight data bits, one stop bit, no parity and any address recognized, but these values can be easily changed by the user. The modules are designed to be compatible with all popular computers utilising RS-232 or RS-485 port and no software is necessary to start using them, although the utility software is provided. The D5300 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D5000 series modules to build a low cost data logger or a data acquisition system for given application.
