The SE Relays 820 series, time delay relay offers 10 different timing functions with ultra-wide timing range of 10 ms to 10 days and meets most timing requirements. Universal voltage input of 12 to 240 VAC/VDC with contact ratings of 15A, 1/2hp at 1200VAC and 1hp at 240 VAC makes it suitable for wide range applications. Contact configaration is performed by silver alloy contacts as DPDT. Slim modular package 17.5mm and 35-mm DIN-rail mounting is ideal for tight spaces and allows easy installation. 2 LED status indicators shows input indication in green LED and output indication in red LED blinking light as timing status relay or red steady on light as energized relay status. This design is compliant with the European Restriction of Hazardous Substances directive (RoHS).
