Allen-Bradley 190E-MNZ242-CB16X Safety Relay Module

Allen-Bradley 190E-MNZ242-CB16X is a safety relay module in the 190E ECO Starter family from Rockwell Automation, a compact modular device that provides monitored safety outputs for machine control. Built to be used in safety circuits, it accepts inputs from protective devices such as E-stops and safety interlocks and translates them into safe-stop commands, enabling compliant fault detection and safe shutdown of machinery in a wide range of industrial environments. The CB16X suffix identifies this variant within the 190E product line, which is widely distributed by Allen-Bradley and third-party suppliers as part of Rockwell Automation's safety-relay ecosystem; partners emphasize its role in enabling modular safety architectures without requiring bespoke wiring for each application. The MNZ242 portion of the designation distinguishes this model by its configuration within the family, aligning with the 190E’s documented use in monitoring and controlling safety functions in open-start configurations, interlocks, and stop circuits.
