Expansion module with RS485 bus connection to a PLC or a transfer station controller. The module has eight analog inputs, whereby each input can be configured to 0-10V or 0-20mA using a DIP switch. The control function of the inputs is programmed on the controller to be expanded on a system-specific basis. Plug-in spring-type terminals enable quick replacement. Additional modules are connected using ribbon cables. 15 modules of the respective type can be addressed per data string, addressing is carried out using a rotary coding switch. A terminating resistor can be set using a jumper.
