DGH D3200M Modbus Analog Current Output Module Series

DGH D3200M Modbus Analog Current Output Module Series

The D3200M Modbus current output module is part of the DGH's data acquisition module family. This output module converts digital MODBUS RTU 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. Two output signal choices are supported (4-20mA or 0-20mA). The signals can then be used to control annunciators, acutators or other hardware. The D3200M module is a cost-effective model, ideal for simple step function control applications, but unlike the non-MODBUS version D3200 it also features user-selectable output slew rate and a communications watchdosg timer. 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 D3200M 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 D3200M 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.
