In the Ex e version, the MODEX digital out module can control various actuators using 16 digital outputs. During operation, a channel can be short-circuited on the short-circuit proof outputs (short-circuit proof to a limited extent). For example, solenoid valves, contacts and also signal transmitters with 24 V/ max. 500 mA 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 short-circuit or voltage failure can also be transmitted in addition to the user data. This is also displayed on the module itself using LEDs.
