Features Applications Model

Digital inputs as supplement to the integral I/O of the CPUs
For flexible adaptation of the controller to the corresponding task
For subsequent expansion of the system with additional inputs
From +60 °C to +70 °C, max. 50% of the inputs can be controlled simultaneously

Digital input modules allow the connection of the controller to digital signals of the process.
This provides users with the following advantages:
Optimum adaptation:With signal modules which can be mixed as desired, users can adapt their controllers exactly to the relevant task. This avoids superfluous investments. Modules with 8, 16, and 32 input/output channels are available.
Flexibility: If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple.
