PR Electronics 2-Wire HART Temperature Transmitter 30V dc, -40°C to 85°C Operating 6335D2A

PR Electronics 6335D2A Temperature Transmitter is a versatile, intrinsically safe 2-wire HART 5 programmable device designed for precise temperature measurement and control applications. With a maximum supply voltage of 30V dc, it operates reliably within an ambient temperature range from -40°C up to 85°C. This compact transmitter with a diameter of 23.5mm and depth of 104mm is suitable for DIN rail mounting in industrial environments.

The transmitter supports a wide array of input sensor types including thermocouples, 2-, 3-, and 4-wire RTDs, linear resistance signals, and bipolar millivolt signals. Its galvanic isolation of up to 1.5 kVAC protects sensitive equipment and minimizes signal interference. Advanced sensor redundancy ensures continuous process availability and safety even if the primary sensor fails. Additionally, the device features sensor drift detection to maintain the integrity of measurements over time.

Programming is straightforward via the free PReset software, accessible through a standard PC. Users can configure input types, output modes, sensor error detection, and process calibration within minutes. The transmitter delivers a standard 4 to 20 mA output signal along with digital HART communication, facilitating easy troubleshooting and integration into control systems.

Robust construction and approval certifications including FM, EMC 2014/30/EU, EAC Ex TR-CU 012/2011, SIL, CSA, ATEX 2014/34/EU, and IECEX underscore its suitability for hazardous area applications.
