Compact Safety Control
SAFEONE DS
The SAFEONE DS safety switchgear is a compact, configurable module for safe machine monitoring. It combines speed and standstill monitoring via sin/cos or TTL encoders with monitoring of up to three safety circuits. Parameterization and online monitoring as well as a validation function is possible with the GO:BEYOND®.logic configuration software.
