Relay Y3F-SS-124DM 24V DC/250V AC 10A, 4-pin

Y3F-SS-124DM is a compact power relay for PCB mounting designed for switching loads in power and control circuits. Thanks to the 24 V DC coil and NO contact, it is suitable for galvanic isolation of the control part from the switched part and for switching mains and low-voltage loads within the rated parameters.

Safety notice

• There is a risk of electric shock when switching 230–250 V AC; only carry out installation and connection when the power supply is disconnected.
• Observe the insulation distances on the PCB and design the appropriate widths of the conductive paths for the switched current.
• For inductive loads (motors, coils, transformers), use appropriate protective elements (e.g. RC element, varistor, snubber) to limit overvoltage and contact burning.
• Do not exceed the rated voltage and current of the contacts; at higher temperatures and with inductive loads, it is necessary to consider reducing the load capacity.
