Schneider Electric 8501XTD1 Relay

Schneider Electric 8501XTD1 is a NEMA control relay timing attachment (Type X) that adds a pneumatic one-minute off-delay to the 8501X relay family. This timing accessory is designed to be paired with 8501 Type X master relays to extend their functionality with a fixed off-delay while preserving a 1 NO and 1 NC contact configuration. The unit is rated for 10 A resistive loads at up to 600 VAC, enabling it to switch common industrial circuits within the established 600 VAC, 10 A resistive spec of the 8501X series. By adding the pneumatic timer, the 8501XTD1 enables timed disengagement for simple sequencing and controlled release in electrical control systems without replacing the core switching element. The combination maintains the familiar 8501X interface, offering a compact solution for applications that require a precise one-minute off-delay in circuit operations, such as machine tools, conveyors, or control cabinets where reliable timing behavior is essential. In environments that rely on robust, conventional relays, the 8501XTD1 provides a straightforward way to introduce time-based control while staying within the established ratings and design language of Schneider Electric’s Type X products.
