MDO-8, Digital Output Sub-module
The MDO-8 output module is a submodule for the base module CNX21, which is galvanically decoupled by means of optocouplers. It provides eight digital outputs for 24V/0.5A. For the operation in the II/O system, you can install up to four MDO-8s in the four slots of a CNX21 base module. This makes possible a maximum of 32 outputs per CNX21. In addition, you can combine MDO-8s with different modules, e.g. digital inputs.
