The SE Relays TDRPRO series time delay relay offers 10 different timing functions with ultra-wide timing range of 0.1ms to 9990hr with thumb-wheel adjustment dial, helping reduce mechanical deviation for greater accuracy. Universal voltage input of 12 to 240VAC/DC with contact ratings of 12A, 1/3hp at 120VAC and 1/2hp at 240VAC, makes this programmable, multifunction relay ideal in design flexibility. [Delete] Contact configaration is performed by silver alloy contacts as SPDT. Socket compatible mounting option allows to set relay directly to panel and makes it ideal for tight spaces and allows easy installation. Dust cover retains settings and keeps dust out. Two 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. The design is compliant with the European Restriction of Hazardous Substances directive (RoHS).
