The D1600M frequency input module is part of the DGH’s D1000M Modbus sensor to computer interface data acquisition module family. This input module converts the frequency or pulse sensor input signal to digital data, linearises, scales and communicates the values using the Modbus RTU protocol to give digital output. The D1600M frequency input module also contains a digital input. 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 D1600M 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.
