Omron G9KB PCB Power Relays
OMRON G9KB PCB Power Relays are 600Vdc, 50A high-capacity power relays with Bidirectional Switching. The power relays are designed to handle continuous carry current and provide highly effective non-polarized arc-controlled switching to maximize performance. The G9KB PCB power relays feature ≤5mΩ low initial contact resistance and 2.8W low coil power consumption. These power relays operate at 12Vdc and 24Vdc rated coil voltage and +85°C ambient temperature. The G9KB PCB power relays are ideally used in an energy storage system, V2X, and DC household appliances.

As fun as is it to try and connect two high-voltage cables together with a seriously undersized transistor, product safety laws require that engineered products don’t go boom every time they turn on. To facilitate in such situations, the G9KB relays are at your service with their maximum output switching of 600Vdc at 50A and maximum initial contact resistance of 5mΩ. Additionally, the G9KB range of relays also has a minimum contact gap of 3.6mm to provide excellent insulation during its off state, and the relay comes in both 12V and 24V coil options which makes them compatible with most industrial systems. Finally, these relays are happy in both cold and hot environments thanks to their operating temperature range of -40°C to +85°C, and they are UL 60947-4-1 and EN 61810-10-certified.
