Omron G7Z Series Power Relay, 24V Coil Voltage, 40A Switching Current - G7Z-4A DC24


This power relay is a Compact electromechanical switching device designed for industrial control and automation tasks, providing high-current switching capability for both AC and DC circuits. It operates from a 24V Coil and is intended for secure installation using screw or DIN‑rail mounting in equipment racks and control panels.

Features and Benefits:


• 40A switching current enables heavy load control
• 480V AC switching supports high-voltage AC applications
• 125V DC switching allows reliable DC circuit interruption
• 4PST‑NO contact arrangement permits simultaneous multi-circuit switching
• 3.7W Coil consumption reduces driver power requirements
• Silver‑alloy contacts deliver improved conductivity and wear resistance

Applications


• Suitable for heater control 40A relay in industrial boilers
• Ideal for motor starter control in automated machinery
• Used for multiple-circuit switching in control panels with DIN‑rail mounting
• Can be used for DC power distribution switching in battery systems

What mounting options are available for installation?


It accepts screw mounting or attachment to a DIN rail, allowing panel or rail fitting in control enclosures.

What electrical Interface does it use for connections?


Terminals are screw‑type, providing secure clamping for power and control conductors.

What Coil characteristics affect driver design?


The Coil draws 3.7W and measures 156Ω, so driver circuitry must supply 24V at the corresponding current.

How does contact material influence longevity?


Contacts MADE from a silver alloy reduce contact resistance and help maintain switching performance under high-current duty.
