Overview, Continued
Safety Relay Circuit With 5 Safety Outputs Using 700S-CF Safety Control Relays
• Circuit complies with EN 954 categories 1, 2, 3
• Use for E-stop control. E-stop will work properly if any one fault occurs (a fault could be one welded contact or one undesired
open connection such as a loose wire).
• Prevents restart of the 5 safety outputs if there is a single fault anywhere in the system.
• High output switching capability and long contact life.
• Provides greater user flexibility for the number of N.O. and N.C. contacts.
Use (3) 700S-CF relays and this diagram to construct the circuit.
➊ Numbers shown are the line numbers where the contacts for this relay appear.
