Stand-still/speed relays

Stand-still/speed relays monitor the rotation of drives to generate a control signal at zero speed or when a set speed is exceeded.


• Prewired rail-mounted modules
• Safety category 3 acc. to EN 954-1
• Positively driven output contacts
• Connection monitoring of the proximity switches
