The RTD-7833 is a space-saving industrial I/O module. It provides for save cable connections due to the use of WAGO Cage Clamp connecters rather than screw terminals (which, even if properly torqued at installation time, might loosen, especially whenever there are vibrations or significant changes of temperature).

A high retention USB connector allows for 50% more retention force than the standard USB preventing accidental disconnect.
