Main unit UE44-3SL Sick UE44-3SL2D33 (6024907)

Safety relays
Main unit UE44-3SL   Model Name UE44-3SL2D33 Part No. 6024907   Самое главное Ideal for the evaluation of safety switches with a mechanical interlock Cross circuit detection and sequence monitoring at the dual-channel input signal 2 N/O contacts for a direct integration into a machine environment 1 N/O contact for a magnetic release, time delayed up to 30 s Manual or automatic reset Coded version for all plug-in positions Преимущества Complete monitoring and analysis of sensors Time delay provides optimal protection of locked doors Adjustable time delay at the front of the device (up to 30 s) makes it easy for the user to change settings Tool-free exchange via coded pluggable terminals Combines the advantages of classic relays and easy circuitry
