- safety critical, 9 contacts Datasheet Features Instantaneous relay Safety critical relay Weld resistant Weld no transfer safety contacts standard Plug-in design with secure locking feature 9 double break contacts in all NO and NC combinations Contact life (mechanical) of 00 million cycles -40 C to +80 C operating temperature Benefits Description The CK safety critical, weld resistant and safety critical relay has 9 double break contacts (Form X & Y - per customers specification) in all NO and NC combinations. Weld no transfer and silver tin oxide safety contacts are standard. The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement). Proven reliable in heavy duty application Long life cycle Easy to maintain and replace Used in safety critical application Low life cycle cost The resistance to impact and vibration is conforming the standards for Railway Transported Equipment. Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay. In power interruption situation relay armature will assume a safe position whatever is the relay operating position due to the strength of the compressed spring which pushes the armature back in the rest position. The CK relays is pluggable in the COR NJ socket. Application The CK relay is designed to offer ultra-compact space saving size for safety critical applications where a high degree of resistance to welding is required. Stationary contacts are silver tin oxide. Mobile contacts are hard silver laminated to copper.

Contact design Weld no transfer function: Double break contacts If one NO contact welds, no NC contact can close (and vice versa) and cause an overlapping of functions. A type test is realized to insure the relays meet this important safety requirement. 50% of max. operating voltage is applied to the relay while holding NC contact closed by mechanical means. Under these conditions, it is verified that no NO contact makes. A B C0 D0 Extend the contact life on highly inductive DC currents. A B 4

Mechanical keying of relay & socket Mechanical keying of the relay to the socket is accomplished during manufacture. Keying slots are located by their keying code numbers on the relay board. Keying rivets are located in the steel socket frame in the correct (and corresponding) coded rivet holes to mate with the relay. Once keying has been completed during manufacture, it is permanent and cannot be changed. This is intentional in the design to insure that only the correct relay can be plugged into the socket. They keying is completed by a color code on the top of the relay cover and on the side of the socket for better identification on the train. They keying details are illustrated below. I.D. Plate Relay shown in position just prior to relay terminals 69 47 Keying board (securely riveted to relay) Factory machined key slots Coded rivet holes Relay terminals 47 69 Welded steel socket frame Socket Factory installed keying rivets Permanently marked keying code on both relay and socket 3
User specifications Installation Install socket and connect wiring correctly according identification to terminals. Plug relay into socket. Reverse installation into socket not possible due to mechanical blocking by locking spring bracket. Don t reverse polarity of coil connection. Relays can be mounted tightly next to each other. Warning! Never use silicon spray near by relays Operation Before operating always apply voltage to coil to check correct operation. Long term storage may corrode the silver on the relay pins. Just by plugging the relay into the socket, the female bifurcated receivers will automatically clean the corrosion on the pins and guarantee a good connection. Do not use the relay in places with flammable gas as the arc generated from switching could ignite gasses. Maintenance Correct operation of relay can easily be checked as transparent cover gives good visibility on the moving contacts. When the relay doesn t seem to operate correctly, please check presence of coil voltage. Use a multimeter. If LED is used, coil presence should be indicated. If coil voltage is present, but the relay doesn t work, a short circuit of a suppression diode is possible (The coil connection may-be reversed). If relay doesn t work after inspection, please replace relay unit by a similar model. Send defective relay back to manufacturer. Normal wear and tear excluded. 4
