Datasheet

Omron G7Z Series Power Relay, 24V Coil Voltage, 25A Switching Current - G7Z-3A1B-20Z-R 24VDC

This power relay is a Compact switching device designed for industrial control and automation systems where reliable high-current switching is required. It operates from a 24V DC Coil and provides multiple contact arrangements to control AC or DC loads in machinery and electrical panels. The unit is intended for panel-mounted or DIN-rail installations and is suited to environments that demand robust electrical switching without complex installation.

Features and Benefits:

• 3.7W Coil power reduces driver load on control circuitry
• 156Ω Coil resistance enables predictable Coil current
• 25A switching capacity handles substantial load currents
• Silver alloy contacts improve conductivity for heavy-duty switching
• Screw terminals allow secure, vibration-resistant connections
• 480V AC and 125V DC ratings support AC and DC load switching

Applications

• Suitable for motor control in factory automation panels
• Ideal for switching resistive and inductive loads in control cabinets
• Used for power distribution in industrial machinery systems
• Can be used for signalling and interlock circuits in electrical assemblies

What mounting options are available for installation?

The unit can be fixed using screw mounting or attached to a DIN track to suit panel or rail installations.

What Terminal arrangement should I expect for wiring?

Terminations are provided as screw-type terminals to ensure firm clamping of conductors under vibration.

What operating temperature range is acceptable for use?

The relay functions within a lower limit of -25°C up to a maximum of 60°C for typical industrial environments.

How does the contact configuration support circuit design?

It provides both multiple normally open and normally closed contact arrangements to accommodate different switching logic and safety interlocks.
