Base modules
The modular and programmable safety controllers are available in different variants.
Safe masters and slaves in the modular series
In the SMX series, the SMX Modular provides a standardized solution for all machine safety tasks. With the PLC commands and more than 280 type-tested safety functions, even complex machining and production centers can be safeguarded easily and transparently.
The decentralized system architecture of the SMX Modular with its master, I/O and technology functions allows a high degree of expansion with up to 32 slaves and just as many drive axes.
