24 V DC Industrial Relays

24 V DC Industrial Relays prices and range: 5 models with current prices, stock status and specifications at Welibaba. Industrial relays are electromechanical relays used plugged into a socket inside a panel, whose changeover (CO) contacts change position when the coil is energized. In machine and plant panels they act as a coupling (interface) between a PLC output and a field device; they drive loads such as contactor coils, solenoid valves and pilot lights. The category includes Siemens coupling relays and their accessories such as the LED module, Finder 46 series miniature industrial relays and Molwex relays; slim relays with a narrow housing and standard relays with 2 and 4 contacts are in separate subcategories. The product data shows 1, 2, 3 and 4 CO contact arrangements, contact currents such as 8 A and 16 A, 8, 11 and 14-pin configurations, and coil voltages such as 24 V DC and 230 V AC. Select the coil voltage and type (AC or DC) according to the control voltage, the number of contacts according to the circuit diagram, the contact current according to the current of the load and whether it is inductive, and the number of pins according to the socket you will use. Because the relay and socket may be sold under different stock codes, verify the set contents on the product page.
