DIN-rail star-delta control relay with adjustable star time (0.1–600 s) and star-to-delta transition (50–130 ms) — SPDT output with neutral centre position for clean contactor sequencing.
Key advantages
- Purpose-built star-delta — Star dwell plus adjustable neutral-centre transition before delta.
- Star 0.1…600 s — Four knob ranges; star-to-delta delay 50–130 ms.
- Neutral centre contact — SPDT with centre-off between star and delta positions.
- Supply choices — M24 (24–240 VAC/DC) or M40 (380–415 VAC); plug-in PAC01 sibling.
- Compact DIN — 22.5 mm housing; ≤0.2% repeatability; UL/CSA.
Typical applications
- Star-delta motor starters on pumps, fans, and compressors.
- OEM motor control panels needing an adjustable Y-Δ timer.
- Retrofits replacing pneumatic or fixed star-delta timers.
- High-line 380–415 VAC control circuits (M40 versions).
Selection guide
- Supply — DAC01CM24 multi-voltage vs DAC01CM40 380–415 VAC.
- Mounting — DIN DAC01 vs plug-in PAC01.
- Star time — Match motor open-transition needs within 600 s.
- Transition — Set 50–130 ms centre-off for contactor overlap avoidance.
Common mistakes
- Using a generic on-delay instead of a true star-delta timer with centre-off.
- Setting transition too short for the contactor pair — risk of short circuit between star and delta.
- Ordering M24 for a 400 V control transformer secondary that needs M40.
- Ignoring ≥200 ms supply interrupt for full reset of the sequence.
When to RFQ / what to tell us
- DAC01C M24 vs M40 (or PAC01); quantity; ship-to.

FAQ
Q: Why a neutral centre position? A: It opens both star and delta paths briefly during the adjustable 50–130 ms transition so contactors do not overlap.
Q: DIN or plug-in? A: DAC01 is DIN-rail; PAC01 is the plug-in sibling.
Q: What should I send for a quote? A: M24 vs M40, DIN vs plug-in, quantity, ship-to.
