Description

The MODEX RTD in Ex i module enables an intrinsically safe connection of 4 Pt100, Pt1000, resistors or potentiometers. The inputs are galvanically isolated from each other, from the power supply and from the bus. The module is connected to the process control system via the PROFIBUS-DP. This is also displayed on the module itself using LEDs. Diagnostics data indicating the status of the outputs with respect to a disconnection or short-circuit can also be transmitted in addition to the user data. This is also displayed on the module itself using LEDs.
