In the Ex i version, the MODEX 8 relay out module can activate various actuators using 8 outputs. It is possible, for example, to directly activate intrinsically safe solenoid valves or other intrinsically safe circuits. The module is connected to the process control system via the PROFIBUS-DP. Coding rotary switches are available for addressing the module.
