DGH D8100 Analog Voltage Input USB Module

DGH D8100 Analog Voltage Input USB Module

The D8100 7-channel voltage input module is part of the DGH's D8000 data acquisition module family with USB interface. This input module measures signal across six different voltage ranges (±25mV, ±50mV, ±100mV, ±1V, ±5V and ±10V) and each channel can be programmed for a different range. It then continuously converts the data at the rate of up to 25/20 conversions per second, storing the latest result in the buffer. The D8100 modules communicate in MODBUS RTU protocol; the data can therefore be retrieved by sending a MODBUS query to the module from the host computer. The D8100 voltage 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 D8100 module is compatible with any commercial software supporting Modbus RTU protocol and is DIN-rail mountable (MK-1 mounting kit required). Combined with other D8000 series modules, a complete, customised data acquisition system can be built easily.
