Description

With the MODEX 4 x digital out Ex i/8 x Ex i digital in, it is possible to control 4 Ex i valves while simultaneously importing NAMUR limit switches via 8 digital intrinsically safe inputs. The statuses of the control and end position signals are displayed using LEDs. The output on the short-circuit proof outputs will be switched off automatically by temperature monitoring in the event of a shortcircuit (short-circuit proof). 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.
