Omron G3NA-410B-UTU 5-24VDC Series Solid State Relay, 10 A Load, Surface Mount, 480 V ac Load, 4V dc Control

This solid-state relay provides silent, contactless switching for AC loads using a DC control signal. It is designed for surface mounting and offers single-pole single-throw normally open operation suitable for industrial control and automation environments. The device employs zero-cross switching to reduce electrical stress during turn-on and is intended for moderate-power applications where compact, screw-terminal connections are required.

• 10 A load capacity enabling medium-current switching
• 480V AC maximum load voltage for high-voltage compatibility
• 5-24V control range allowing flexible DC drive levels
• Zero-cross switching reduces inrush and electromagnetic interference
• 100 mΩ on-state resistance minimises conduction losses
• 5 mA off-state leakage current limits unwanted load energisation

• Suitable for resistive heater control in process equipment
• Ideal for motorised valve switching in automation panels
• Used with PLC outputs for non-mechanical load switching
• Can be used for lighting control in industrial installations
• Suitable for temperature control systems in production lines

Screw-type terminals are provided for both control and load connections to facilitate secure electrical and mechanical attachment.

The device is rated to operate from -30 °C up to 80 °C, so ventilation and heat dissipation should be considered in high-temperature installations.

Because it uses zero-cross switching, the relay commutates the AC load near the voltage zero crossing, reducing switch stress and electromagnetic interference during energisation.

The relay is intended for surface mounting and has a Compact footprint with a width of 43mm and a height of 58mm to assist tight panel layouts.
