Datasheet

Omron G7Z Series Power Relay, 12V Coil Voltage, 40A Switching Current - G7Z-4A-11Z-R 12VDC

This power relay is a four-pole switched device designed for control and switching tasks in industrial automation and electrical systems. It operates from a 12V DC Coil and is intended for installations requiring high-current switching in both AC and DC circuits. The unit is compatible with screw and DIN-rail mounting and meets RoHS requirements for material restrictions.

Features and Benefits:

• 40A switching current handles heavy-load circuits
• 480V AC switching voltage enables high-voltage AC control
• 125V DC switching voltage supports DC power switching up to 40A
• Silver-alloy contacts reduce contact wear and ensure conductivity
• 12V DC Coil consuming 3.7W provides predictable actuation power
• Screw-terminal connections simplify secure wiring installation

Applications

• Suitable for motor control panels requiring high-current switching
• Ideal for industrial automation relays in control cabinets
• Used for switching DC power supplies in battery systems
• Can be used for load switching in HVAC and building services
• Used with DIN-rail assemblies for modular control systems

What is the Coil resistance and how does it affect drive requirements?

The Coil presents 39Ω resistance

at 12V DC this produces the specified 3.7W Coil power, so drivers must supply adequate current for reliable actuation.

Which Terminal arrangement is provided for cabling?

Termination is via screw-type terminals designed for robust conductor clamping in industrial environments.

What temperature range can this device operate within?

It is rated for continuous operation down to −25°C and up to 60°C ambient, suitable for typical indoor industrial settings.

What contact resistance should be expected in circuit calculations?

Closed-contact resistance is specified at 400mΩ and should be included when calculating voltage drop and heating in high-current paths.
