FlexTop 2231 is a Profibus® PA configurable universal transmitter with galvanic isolation between input and output. The input can be configured for RTD or T/C sensors, resistance, current or voltage signals. 2, 3 or 4 wire as well as dual Pt100 connection can be selected for the resistance input. Selecting the latter it can be confi gured for a differential, average or average with redundancy output signal. The built-in temperature sensor or a remote Pt100 sensor can be used to compensate for “cold junction” (CJC) if thermocouples are connected. FlexTop 2231 is embedded in silicone which makes it resistant to humidity. FlexTop 2231 has a compact design in a ø44 mm enclosure for installation in a DIN-B housing, Bourdon-Haenni ø80 mm stainless steel housing or similar. It has a 6 mm center hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments. FlexTop 2231 is designed according to the Profi bus® PA profi le ver. 3.0 and is fully configurable via Simatic® PDM® software. The Profi bus® PA communication features on-line process monitoring, transmitter confi guration and multiple process control in 2-wire networks especially suited for Ex applications.
