Siemens S7-200 EM 231 Analog Input signal modules allow the connection of the controller to analog signals of the process. This provides users with optimum adaption; with analog signal modules users can optimally adapt their controllers even to more complex tasks. Sensors can be connected directly, with up to 12 bit resolution and different input ranges permit the connection of sensors without the need for an additional amplifier. If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple.
