The A1240E is a panel-mount solid-state relay rated for 25A output current at 24-140 VAC operating voltage with 18-36 VAC control input. It features SCR output technology optimized for heavy industrial loads, with zero voltage or instantaneous turn-on switching options. The relay incorporates a direct bond copper substrate, improved SEMS screw and washer design, and anti-rotation barriers in a redesigned housing. It is UL/CSA/TUV approved and CE compliant to EN60950-1, with EMC compliance to Level 3. The A1240E is ideal for industrial automation, motor control, and load switching applications requiring reliable AC switching with low on-state voltage drop of 1.15 Vrms and thermal resistance of 0.8°C/W.
