DGH D1300 Sensor to Computer Interface Thermocouple Input Module Series

DGH D1300 Sensor to Computer Interface Thermocouple Input Module Series

The D1300 thermocouple input module is part of the DGH's D1000 sensor to computer interface data acquisition module family. This input module converts the thermocouple temperature sensor input signal from the choice of 8 different thermocouple types (J, K, T, E, R, S, B and C) to digital data, linearises and scales it in °C or °F, and communicates the values using the ASCII protocol to give digital output. The D1300 thermocouple input module also contains two digital inputs which may be read by the host computer to sense the state of a remote digital signal, such as state of limit or safety switches, a 60Hz events counter (not applicable for D1300M) and three open-collector digital outputs (or HI/LO alarms) which may be controlled by the host computer and used to control, for example, solid-state relays. 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 D1300 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 D1300 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.
