Omron Power PCB Relay G8PT Datasheet Summary

The Omron Power PCB Relay G8PT datasheet details a compact relay with up to 30 A switching capacity, designed for a range of applications including home and industrial appliances, HVAC systems, and more. The relay features two main models: the G8P-1A4P-BG offering a 2.0 mm contact gap and a high dielectric strength of 4,000 VAC, and various other models with different contact forms and constructions such as SPST-NO, SPDT, open frame, and sealed types. The sealed models come with a ventable nib.

Ordering Information

To order the relay, one must select the part number and add the desired coil voltage rating, such as G8P-1A4P-DC12 for a 12V DC coil. There are various mounting types including PCB, flange mount, and quick-connect load terminals with different contact forms noted as SPST-NO and SPDT. The datasheet specifies that the “BG” model is available with 12 VDC and 24 VDC coils only and is packaged with 50 pieces per tray.

Contact and Coil Data

The contact data provided in the datasheet shows a rated load of up to 30 A at 250 VAC or 20 A at 28 VDC, with the BG model having a slightly lower capacity. The contact material is Ag-Alloy, and the rated carry current reaches 30 A. Information on the minimum permissible load, operating voltages, and maximum switching capacities is detailed alongside. Coil data shows rated voltage, current, resistance, and power consumption figures, with specific emphasis on the relay’s 75% maximum pick-up voltage, 10% minimum dropout voltage, and 120% maximum voltage.

Performance Characteristics

Performance characteristics like contact resistance, operating times, and dielectric strength are summarized, indicating the relay’s robustness in various conditions. A standout feature includes the product’s impulse surge withstand of 6 kV. Other specified characteristics include vibration and shock resistance, ambient operating temperature and humidity ranges, and service life expectancy both mechanically and electrically.

Note on Discontinuation and Compliance

Notably, the datasheet announces the discontinuation of the Power PCB Relay G8PT at the end of April 2015. This relay adheres to standards set by recognized entities such as UL, CSA, and VDE and complies with RoHS environmental regulations.
