SSAC
SCR430T - SSAC Univ Lamp Alarm 120VAC Relay for Beacon Obstruct The SCR Series Family The SCR series is a universal lamp alarm relay designed to sense the failure of flashing or steady incandescent beacon lamps or steady side lights. The toroidal current sensor provides isolation and allows monitoring of more than one line at a time. The SCR Series energizes when one or more lamps fail. It will monitor the operation of one to four side lights and up to four beacon lamps. Operation When a lamp fails, the SCR Series senses a decrease in current flow. After a fixed time delay, the LED glows and the two alarm outputs energize. The outputs and the LED are reset when the failed lamps are replaced and the current returns to the nominal setting, or when the input voltage is removed. The SCR will sense an open flasher, it will not sense a continuously ON flasher (see FB Series). Features : Monitors incandescent lamps for failure Senses failed flashing beacon or obstruction lamps Switch selectable number, voltage, & wattage of lamps Isolated, 10A, SPDT alarm output contacts 1A, solid-state line voltage alarm output Toroidal current sensing Download the The SSAC Product Line catalog in *.pdf format Download the The SCR Series Datasheet datasheet in *.pdf format
