STO Safety Module

Safety Module STO (Safe Torque Off) is an expansion add-on for item Controllers in the C series. It ensures that, when at rest, the Motor does not produce any effective torque. This means the system is shut down safely when, for example, the emergency shutdown button is pressed or a door is opened. The Module is slotted into one of the expansion slots. All applicable safety standards are reliably met, including category 4/PLe to EN ISO 13849-1 and SILCL 3 to EN 62061.
