The RIZUR-DCS-2 explosion-proof digital thermoregulator manufactured by OOO «NPO RIZUR» complies with ТU-3443-001-12189681-2014, GOST R МEК 60079-0-2011, GOST R МEК 60079-11-2010, GOST IEC 60079-1-2011 standards for electric equipment with explosion protection type “Flameproof Enclosure (d)”, “Intrinsically Safe Circuit (i )”, “Intended for Use in Explosive Gas Atmospheres ”, and has 1Exd[iaIICGa]IIBT6GbX explosion-proof marking. RIZUR-DCS-2 is supplied together with digital temperature sensors RIZUR-DT with 0ExiaIICT6GaX explosion-proof marking. According to the explosion-proof marking, Ch. 7.3 of Electrical installation code (PUE) and other regulations governing the use of electrical equipment in ex-areas, the heater is certified for use in ex-areas of internal and external facilities.
RIZUR-TB explosion-proof thermoregulators are used for control and maintenance of required ambient air temperature in heating/cooling systems that protect the equipment against excessively high/low temperatures and significant fluctuations that are averse to time and stability of performance of such control and measurement equipment.
Thermoregulator RIZUR-TB-DCS is manufactured on the base of a digital control system. The module consists of a microcontroller (regulated by the software) and remote digital air temperature indicator RIZUR-DT or RT 100 (the immersible version can be used for the temperature maintenance in the liquid media).
The hardware-software solution ensures that the temperature will be maintained within the accuracy of 1 °С. The temperature parameters are programmed at the manufacturing facility on the basis of the ordering information. For the purpose of signalizing when the temperature surpasses the set limits, thermoregulator RIZUR-TB-DCS has additional relay outputs, as well as, depending on the design version, an analogue output signal 4-20mА.
The housing of the thermoregulator also performs the function of a junction box, meaning that there's a terminal block inside and Ex-protected cable glands for power cables, heater, and temperature sensors outside.
Thermoregulator RIZUR-TB-DCS is designed specifically for controlling heating elements of high power (up to 5kW), including self-regulating heating cables.
The thermoregulator can withstand the cold starting loads that surpass the nominal power load in 10 times. Download description
