Ambient Temperature
-25 °C to +60 °C at T4Description
In the Ex i or Ex e version, the MODEX 8 x 4 to 20 mA module can control various actuators depending on the model using 8 analogue short-circuit proof outputs. The controlled actuators can be switched off by an emergency stop via a second power supply connection on the module on terminals U- and U+. 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.
