Air-O-Tronics TDR-1015A1 Solid State Timer

Air-O-Tronics TDR-1015A1 Solid State Time Delay Relay is a 120 VAC timer that delivers a precise 0.2 to 15 second delay before energizing its output. Built around a solid‑state timing circuit, the unit is rated to switch loads up to 10 A, making it suitable for short-delay control in HVAC and refrigeration systems as well as general industrial automation. When power is applied or a trigger is received, the timer counts the configured interval and then allows current to flow to the connected device, enabling sequenced start‑ups or safe inrush control. This model is part of Air‑O‑Tronics’ line of time‑delay relays designed for compact, reliable on‑delay operation in environments that demand repeatable timing with a simple 120 VAC supply and a well defined 0.2–15 s window.
