DGH DIN-130 Modbus Thermocouple Input Module Series

DGH DIN-130 Modbus Thermocouple Input Module Series

The DIN-130 MODBUS thermocouple input modules are part of the DGH's DIN-100 data acquisition module family. This input module converts analog input signal from the choice of eight different thermocouples (J, K, T, E, R, S, B and C) using the MODBUS RTU protocol to digital data at the rate of 8 conversions per second, storing the latest result in the buffer. The signal is transmitted to the computer or other processor-based controlling equipment using RS-485 port; if this is not available a DIN-191 converter to RS-232 can be used.  The DIN-130 module can be directly connected to a sensor and perform signal conditioning, linearisation, scaling and conversion to both ASCII and MODBUS values. 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 DIN-130 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 require no special software and can be connected and started up quickly and easily, however a utility software is available at no extra charge if required. The DIN-130 can be mounted on a DIN-rail directly, without need for a mounting kit.
