The A1240 is a panel-mount solid-state relay featuring SCR output technology rated for 25 amperes at 24-140 VAC operating voltage. It accepts 90-280 VAC control input and provides zero voltage or instantaneous turn-on switching options for flexible application requirements. The relay incorporates a direct bond copper substrate, improved SEMS screw and washer design, and anti-rotation barriers in a redesigned housing, with maximum on-state voltage drop of 1.15 Vrms at rated current and thermal resistance of 0.8°C/W junction to case. It is UL/CSA/TUV approved and CE compliant to EN60950-1, with EMC compliance to Level 3, making it suitable for heavy industrial loads, motor control, and power distribution applications requiring reliable solid-state switching.
