MSSI-2, SSI (Synchronous Serial Interface) Sub module

Product Description

The MSSI-2 input module is a submodule for use in a base module and it provides two synchronous serial inputs.

For operation in the II/O system, you can install up to four MSSI-2s in the four slots of a base module. This makes possible a maximum of 8 SSI inputs per base module. In addition, you can combine MSSI-2s with different modules, e.g. digital outputs.
