© Siemens AG 2016 Temperature Measurement Transmitters for rail mounting SITRANS TR300 two-wire system, universal, HART ■ Overview ■ Application SITRANS TR300 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets. The following sensors/signal sources can be connected over their universal input module: • Resistance thermometers (2, 3 or 4-wire system) • Thermocouples • Resistance-based sensors and DC voltage sources The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic, superimposed by the digital HART signal. Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices comply with the Directive 2014/34/EU (ATEX). ■ Function "HART" to beat - the universal SITRANS TR300 transmitter • Two-wire devices for 4 to 20 mA, HART • Device for rail mounting • Universal input for virtually any type of temperature sensor • Configurable over HART ■ Benefits • • • • • • • • • • • Compact design Electrically isolated Test sockets for multimeters Diagnostics LED (green/red) Sensor monitoring open circuits and short-circuits Self-monitoring Configuration status stored in EEPROM Expanded diagnostic functions, such as slave pointer, operating hours counter, etc. Special characteristic Electromagnetic compatibility to EN 61326 and NE21 SIL2 (with Order code C20), SIL2/3 (with C23) The SITRANS TR300 is configured over HART. This can be done using a handheld communicator or even more conveniently with a HART modem and the SIMATIC PDM parameterization software. The configuration data are then permanently stored in the non-volatile memory (EEPROM). Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case of a sensor short-circuit, the LED flashes red, an internal device fault is indicated by a steady red light. The test socket can be used to connect an ammeter at any time for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

An additional error is generated in the output current 4 to 20 mA as a result of the digital/analog conversion of 0,025 % of the set span (digital-analog error). The total error under reference conditions at the analog output is the sum from the digital error and the digital-analog error (poss. with the addition of cold junction errors in the case of thermocouple measurements). 2/150 Siemens FI 01 · 2016 © Siemens AG 2016 Temperature Measurement Transmitters for rail mounting SITRANS TR300 two-wire system, universal, HART ■ Selection and Ordering data Accessories Article No. Temperature transmitter SITRANS TR300 MiniDVD for temperature measuring instru- } ments A5E00364512 For mounting on a standard DIN rail, two-wire system, 4 … 20 mA, HART, with electrical isolation, with documentation on MIniDVD With documentation in German, English, French, Spanish, Italian, Portuguese and SIPROM T parameterization software Article No. • Without explosion protection } 7NG3033-0JN00 • With explosion protection to ATEX } 7NG3033-1JN00 Further designs Order code Please add "-Z" to Article No. with and specify Order codes(s). 2 HART modem } • With USB connection Simatic PDM operating software 7MF4997-1DB See Section 8 } Available ex stock.
