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.8 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 15-bit resolution plus sign and is transmitted with high interference resistance. Both modules are connected to the process control system via the PROFIBUSDP. 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.
