Application for RTD-Box TR1200 (RS485) : 7XV5662-6AD10
|
This document describes the measurement of 12 temperatures in a 7SJ62x via the RTD-Box TR1200 at an RS485-Bus.The RTD-Box TR1200 has 12 sensor inputs and can in this way measure 12 temperatures via Pt 100-elements.
2 and 3 conductor Pt 100 are supported. In the case of 2 conductor operation, the measured line resistance can be compensated with an applicable setting. All settings are done with 3 keys on the front cover. Input can be blocked with a code. The measured value output to the protection device is done with the bus cable 7XV5103-7AAxx via a RS485-Bus. Note: SIPROTEC 4 protection devices can process up to 12 measured values. Up to now, 2 RTD-Boxes TR600 were required. The RTD-Box TR1200 can now replace up to 2 RTD-Boxes TR600 for temperature measurement. Note: The TR1200 does not supply its own alarm messages or contacts. The alarm levels must be set and displayed for each input in the protection device, and output via contacts or transferred to a central control system. |
