ADW1124HTW Panasonic DW Relay – 1 Coil Latching, 16 A 277 V AC, 100 A Inrush, 24 V DC
The Panasonic ADW1124HTW is a compact polarized power relay from the DW series, with a 1-coil latching design and a 24 V DC coil. Because it latches, a short pulse is enough to set or reset the contact, and the contact then stays in position with no continuous coil current. This makes it ideal for energy-saving designs such as smart meters, lighting control, security equipment, home appliances and industrial controls. This is the inrush type: its 1 Form A contact switches 16 A at 277 V AC and withstands 100 A inrush current, rated for tungsten lamps and electronic ballasts. It is also the IEC 60335-1 compliant version. With 5,000 Vrms between contact and coil and a 12,000 V surge withstand, it provides strong isolation in a small 8 g PCB package.
