Finder 20.28.9.024.4000 impulssirele 24V AC/DC 2NO 8A

In electrical control circuits, a standard relay returns to its rest state when power is removed. The Finder 20.28.9.024.4000 solves the need for a switch that holds its position without continuous coil power, reducing energy consumption and heat in panels.

Who is it for

Panel builders and electricians who need a compact, DIN-rail mountable impulse relay for lighting, shutter, or general load control where a maintained contact state is required.

Main features

• Bistable latching relay with 2 normally open contacts
• Coil voltage 24 V AC/DC, suitable for mixed control circuits
• Rated contact current 8 A at 250 V AC
• Reinforced insulation between coil and contacts
• Screw terminals for secure wiring

Specifications

• Contact configuration: 2 NO
• Rated load (AC1): 2000 VA
• Contact material: AgNi
• Coil power: 1.2 VA (AC) / 0.8 W (DC)
• Dielectric strength coil-contact: 4 kV AC
• Electrical life at rated load: 100,000 cycles
• Mechanical life: 1,000,000 cycles
• Operating temperature: -40 to +40 °C
• Mounting: DIN rail 35 mm
• Protection degree: IP20

Tips

Use a momentary pushbutton to pulse the coil; the relay will latch and hold the load until the next pulse. Ensure the control voltage matches 24 V AC or DC as required.
