Schneider Electric 9050-AO-10D Pneumatic Timing Relay

Schneider Electric's Square D 9050-AO-10D Pneumatic Timing Relay is an on-delay timer from the Type A family that delivers 0.1 to 60 seconds of timing in control circuits. It uses a 110/120 VAC coil (50/60 Hz) and features SPDT contacts (1NO/1NC) rated for up to 15 A at 600 V, making it suitable for sequencing relays, motors, and other loads in industrial automation. As part of Schneider Electric’s 9050 family of pneumatic timers, the AO-10D model provides a compact, field-serviceable timing solution designed for standard control voltages and rugged operation in demanding environments. Typical applications include introducing a controlled delay before energizing a load to ensure proper startup sequencing and to prevent voltage transients on machines, conveyors, and interlock systems.
