DGH D1600 Sensor to Computer Interface Frequency Input Module Series

DGH D1600 Sensor to Computer Interface Frequency Input Module Series

The D1600 frequency input module is part of the DGH's D1000 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 ASCII protocol to give digital output. The D1600 series includes frequency, timer, 60H events counter (20Hz available upon request) and accumulator (combination of frequency/timer with events counter) models. The D1600 frequency input module also contains a digital input (acting as the events counter on 160x and 161x modules). 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 (this feature excludes the events counter - upon power-up the counter is set to 0). The D1600 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-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. The D1600 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000/D2000 modules to provide complete customised data acquisition system for given application.
