The Finder 77.A1.9.024.8650 is a hockey puck solid state relay with 1A SPST-NO output, rated 25 A at 600 V AC and switching 24 to 660 V AC, driven by a 24VDC input and drawing 25 mA.
Its back-to-back SCR output switches on at the zero crossing, which suits lamps, heaters and solenoids and keeps lamp inrush down.
It carries a lamp rating of 2000 W incandescent/halogen, 800 W LED, 800 W CFL at 230 V.
Its terminals are relay style, with input and output on opposite sides.
It mounts on heat sink 077.21 or 077.13, with thermal pad 077.T1 or 077.T2 (adhesive).
It has Panel mounting and screw terminals.
