Description

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 transmitters or active 4 – 20 mA signals can be imported as signals.4 x 4 to 20 mA in & out Ex i In the Ex i version, the MODEX 4 x 4 to 20 mA module with 4 analogue inputs enables 4 analogue intrinsically safe signals to be fed in or evaluated and additionally the control of intrinsically safe actuators using 4 x 4 to 20 mA outputs. The input signal has 16-bit resolution and is transmitted with high interference resistance. Both modules are 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.
