  • 8 x 4 to 20 mA in/4 x 4 to 20 mA in/out

    8 x 4 to 20 mA in/4 x 4 to 20 mA in/out

    PROFIBUS-Interface for zone 1/21 8 x 4 to 20 mA in Ex i In the Ex i version, the MODEX 8 x 4 to 20 mA module with 8 analogue inputs enables 8 analogue intrinsically safe signals to be fed in or evaluated. For example, intrinsically safe two-wire...

  • 8 x 4 to 20 mA out Ex i/Ex e

    8 x 4 to 20 mA out Ex i/Ex e

    PROFIBUS-Interface for zone 1/21 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...
