The D3100 voltage output module is part of the DGH’s data acquisition module family. This output 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. Six output signal choices are supported (±1V, ±5V, ±10V, ±0-1V, ±0-5V and ±0-10V). The signals can then be used to control annunciators, acutators or other hardware. The D3100 module is a cost-effective model, ideal for simple step function control applications. 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 D3100 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 D3100 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.
