DGH D6400 Analog Volt, TC & Current Input Module

DGH D6400 Analog Volt, TC & Current Input Module

The D6400 7-channel analog input module is part of the DGH's D6000 data acquisition module family. This input module combines all the features of modules D6100, D6200 and D6300, as it measures signals from six different voltage ranges, a current range, and eight different thermocouple types (J, K, T, E, R, S, B and C). It continuously converts the data at the rate of up to 25 conversions per second, storing the latest result in the buffer. The data (unsigned integer percentage of full-scale values) can then be retrieved by sending a Modbus query to the module from the host processor. The D6400 input module can be directly connected to a wide range of sensors and annunciators, and provides all signal conditioning and linearisation, while containing no pots or DIP switches. For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings such as the range, meaning the values are maintained in the event of power loss. The D6400 module is compatible with any commercial software supporting Modbus RTU protocol and is DIN-rail mountable (MK-1 mounting kit required). Combined with other D6000 modules, it provides the complete, customised data acquisition system for given application.
