SMX46 module

The SMX46 module offers a switch matrix of 24 signal 2-wire crosspoints organized into 4 rows and 6 columns. Additional functionalities are two analog outputs and one power relay with two SPDT (form C) switches.

The module has two 16-pin 3.81 mm connectors on the front panel thanks to which it is possible to quickly and easily connect the wires without the need for an additional breakout box. 8-way pluggable female terminal connector blocks in low-profile push-in and screw-fasten variants (not included) can be used to connect the wires.
