Hoofddorp, The Netherlands Omron has announced a power relay designed specifically to control high inrush currents to fluorescent or incandescent lamps in emergency lighting systems and appliance control applications. For example, in home appliances such as refrigerators, building control devices such as lighting circuits, and HVAC equipment such as heating and ventilation control systems. The G5RL-1A-E HR relay is a low profile relay (29.0 x 12.7 x 15.7 mm) capable of handling inrush currents up to 100 A at 240 V AC. The relay is TV5 rated by UL and is approved to 100 A at 240 V AC for 50,000 operations by VDE. It has a rated coil voltage of 5, 12, 14 and 48 V DC allowing 50,000 operations with a resistive load of 16 A at 250 V AC/24 V DC. The relay has a SPST-NO contact configuration and a Flux protective construction. The contact base material is gold alloy for longer life expectancy and high contact reliability. The G5RL-HR relay conforms to VDE (EN 61810-1/EN 60255-23) and UL 508/CSA C22.2 standards. Omron Europe BV , Hoofddorp, The Netherlands. www.omron.com.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
