SMX compact
Safe masters and slaves
in the compact series

Simple and safe - that is what distinguishes this series. From safe I/O processing of a few signals to sophisticated drive monitoring, the SMX Compact solves every safety task safely and compactly.

The safe solution when standards reach their limits!

If things ever become a bit more complex, the SMX Compact (/4x or /DNM) provides the right answer for demanding safety tasks.

In combination with safe fieldbus communication and in conjunction with an F-Host, the SMX Compact (/4 or /DNM) solves tasks such as safe position monitoring, area detection, multi-axis functions and collision monitoring. Communication with any master controller is using safe fieldbus systems such as FSoE or PROFIsafe. It can also respond within 3 ms without bus communication and generate a safe state.
