The D4200 programmable current output module is part of the DGH’s data acquisition module family. This output module, same as the D3200 module, converts digital ASCII signal from a host computer, received via RS-232 or RS-485 ports, to analog DC voltage output at the rate of 1000 conversions per second. On the top of all of the D3200’s features, it offers higher level functions for controlling output slew rates and programmable options, as well as communications watchdog timer. Two output signal choices are supported (0-20mA or 4-20mA). The signals can then be used to control annunciators, acutators or other hardware. These modules utilise 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 D4200 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 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 D4200 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other DGH modules to provide complete customised data acquisition system for given application.
