DGH D1100M Modbus with Voltage Input Module Series

DGH D1100M Modbus with Voltage Input Module Series

The D1100M voltage input module is part of the DGH's D1000M Modbus sensor to computer interface data acquisition module family. This input module converts voltage input signal from the choice of six different voltage ranges (±10mV, ±100mV, ±1V, ±5V, ±10V and ±100V) and continuously converts the data using the Modbus RTU protocol to give digital output at the rate of 8 conversions per second, storing the latest data in the buffer. The data can be retrieved by sending an Modbus RTU command from the host computer. The D1100M voltage input module also contains one digital input and two open-collector digital outputs which may be controlled by the host computer and used to control, for example, solid-state relays. 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 modules are designed to be compatible with all popular computers utilising RS-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. Upon startup, a simple command can be used to setup desired baud rate, parity and other parameters. The D1100M can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000M/D2000M modules to provide complete customised data acquisition system for given application.
