Omron Chassis Power Relay 24V DC Coil 40A Switching Current 4PST G7Z-4A-11Z-R DC24

Omron G7Z-4A-11Z-R DC24 chassis power relay features a 24V DC coil voltage and a 40A switching current capacity, designed for industrial automation and control systems. It is engineered to efficiently switch electrical loads such as motors, inverters, and servo drivers. With its 4PST contact configuration, this relay supports diverse control applications requiring high-current switching capabilities.

The relay is mounted securely using a chassis style installation, providing robust placement with the coil terminal oriented upwards for optimal operation. It consumes 3.7 watts of power with a coil resistance of 156 ohms, operating effectively between -25°C and 60°C.

Its durable silver alloy contacts provide reliable conductivity with a low contact resistance of 400 milliohms, and it supports switching voltages up to 480V AC and 125V DC. The compact size (45mm length, 92.2mm width, and 62mm height) allows easy integration into electrical panels and equipment.

This non-latching relay design facilitates simplified system control without the need for reset operations. It is RoHS compliant and manufactured in Japan, ensuring quality and compliance with safety standards. Maintenance requirements are minimized due to its high contact life of up to one million operations, making it a dependable component for industrial automation applications.
