"Sick UE48-20S2D2 Overview
Safety Relay Module UE48-2OS2D2 
Sick UE48-20S2D2 Description
•Ideal for the evaluation of emergency stop pushbuttons, safety switches, safety light curtains, safety laser scanners and pressure sensitive mats
•Cross circuit detection and sequence monitoring at the dual-channel input **
•2 safety outputs, 1 application diagnostic output
•Manual or automatic reset
•Coded version for all plug-in positions
Your benefits

•One module for all common applications
•Complete monitoring and analysis of sensors
•The sequence monitoring takes over the evaluation of non-contact safety switches
•Possibility of fast diagnostic via the status information
•Fast tool-free exchange via coded removable terminals
•Combines the advantages of classic relays and easy circuitry
