Siemens Automation Relays
Siemens Automation Relays prices and range: 102 models with current prices, stock status and specifications at Welibaba. Automation relays are switching devices that open and close the output circuit with a small control signal applied to their coil or input, and that electrically isolate the two circuits from each other. They are used in machine and process panels to isolate PLC outputs from the load, build interlocking circuits, and switch loads such as contactor coils, solenoid valves or heaters. The category includes socketed general-purpose and industrial relays, PLC and PCB relays, solid state relays (SSR) with no mechanical contacts, step and impulse relays, and relay sockets and accessories; products from brands such as Isıso, ABB, Siemens and Schneider Electric are listed. Select the coil voltage according to the control voltage, the number and arrangement of contacts (normally open, normally closed, changeover) according to the circuit diagram, the contact current according to the current and type of the load, and the pin layout according to the socket you will use. For loads that switch on and off very frequently, such as heaters, solid state relays with no contact wear are preferred; in circuits that require multiple contacts, electromechanical relays are preferred.
