Relay G5V-2, 12V DC/125V AC 2A

The Omron G5V-2 miniature signal relay in standard design is designed for switching low to medium loads in control and automation circuits. Thanks to the DPDT configuration (2× changeover contact), it is suitable for switching two independent signal branches or for galvanic isolation of the control and power parts.

Installation and operating instructions

• When designing, consider the type of load (resistive/inductive) and use appropriate protection elements (e.g. RC element, varistor, diode for DC coils in the external circuit).
• Observe the nominal coil voltage of 12 V DC and the maximum coil voltage limits.
• For long-term reliable operation, verify the switching conditions in a real application (current, voltage, switching frequency, temperature).

Safety notice

• Hazardous voltages may be present when switching 125 VAC or 125 VDC. Perform installation and service only with power disconnected and in accordance with applicable standards.
• Ensure sufficient insulation distances on the PCB and appropriate shielding according to application requirements.
