Description

In the Ex e version, the MODEX 8 x 4 to 20 mA module with 8 analogue inputs enables 8 analogue signals to be fed in. For example, two-wire transmitters can be imported as signals. The input signal has 12-bit resolution and is transmitted with high interference resistance. The module is connected to the process control system via the PROFIBUS-DP. Coding rotary switches are available for addressing the module. 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.
