Teknim TFM-2441 Smart Addressed Internal Isolated Dry Contact Input/Output Module

It is an addressed module that carries four inputs and four dry contact outputs in a single enclosure. Since each address is defined as one input and one output, you can monitor and control four separate points from the same enclosure; in projects with multiple location controls, it saves cable and panel space compared to distributing separate modules. When a short circuit occurs in the loop, the isolator in the housing is activated, and the remaining devices on the line continue to communicate with the panel. It is documented for EN 54-17 and EN 54-18.
