MDIO16-16I, Digital Input Sub-module

Product Description

The MDIO16-16I input module is a submodule, which is galvanically decoupled by means of optocouplers, for the base module. The submodule provide 16 digital inputs 24V. For operation in the I/O system, you can install up to four MDIO16-16Is in the four slots of a base module. This makes possible a maximum of 64 digital inputs per base module. In addition, you can combine MDIO16-16Is with different modules, e.g. digital outputs.
