Schneider Electric 8501XTD1 Timer Attachment

Schneider Electric’s Square D 8501XTD1 Pneumatic Timer Attachment adds a precise 0.2–60 second off-delay timing to a Type X NEMA control relay, enabling timed sequencing of loads without a separate timer module. It provides one normally open and one normally closed timed contact, is rated for 10 A resistive at 600 VAC, and uses screw-clamp terminals for copper wire (AWG 18–12). The timer mounts on 0–4 pole AC or DC relays (excluding the XMO master relay) and is UL-listed and CSA-certified for safety and compliance. Designed for the 8501 family, it delivers an adjustable delay from 0.2 seconds up to 60 seconds, supporting applications that require a compact, coordinated off-delay in industrial control circuits.
