2.3 I/O extension modules
Various I/O extension modules are available for setting up the wireless system quickly and
easily. You can therefore adapt the number and type of signals to the respective application.
Features
– White thumbwheel for easy and tool-free assignment of device pairs (I/O mapping)
– Modular structure via DIN rail connector (hot-swap capability)
– Depending on the module: channel-to-channel electrical isolation
– Depending on the module: analog inputs or outputs (0/4 mA ... 20 mA / 16-bit resolution
/ <0.1% accuracy)
– Depending on the module: digital wide-range inputs or outputs (0 V ... 250 V AC/DC)
– DIP switches for HOLD/RESET behavior of outputs
– Loop power function for passive sensors
For a detailed description of the available I/O extension modules, refer to the pages listed
