The Finder 77.31.9.024.8051 is a 22.5 mm modular solid state relay with 1A SPST-NO output, rated 30 A at 400 V AC and switching 48 to 480 V AC, driven by a 24VDC input and drawing 11 mA.
Its back-to-back SCR output switches on immediately (random switch-on), which suits motor control and finer control needing a short operate time.
It carries a lamp rating of 4500 W incandescent/halogen, 2500 W LED, 2500 W CFL at 230 V.
Its terminals are relay style, with input and output on opposite sides.
It has DIN Rail mounting and box clamp terminals.
