In the Ex i version, the MODEX digital out Ex i module can control various actuators using 16 digital outputs. During operation, a channel can be shortcircuited on the short-circuit proof outputs (short-circuit proof to a limited extent). For example, intrinsically safe solenoid valves and intrinsically safe signal transmitters can be controlled as actuators. 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.
