Schneider Electric's Square D AO-10E Pneumatic Timer Relay is an AC-operated timing device with a 0.1 to 60-second on-delay and a single normally open and a single normally closed (1NO, 1NC) contact set (SPDT) rated to switch up to 600 VAC at 15 A. The timing coil is designed for 110/120 VAC operation at 50/60 Hz, delivering reliable delay control in control circuits. Common applications include motor-start sequencing, valve actuation, and other industrial control tasks where a rugged, electronics-free timer is advantageous.
