Operational voltage limits: 0.85–1.1 Uc; drop-out: 0.3–0.5 Uc. No built-in suppressor module. That means you need an external flyback diode or RC snubber across the coil if you're switching it with a PLC or relay. Skip it and the back-EMF can weld your contacts or fry the output card. The coil's average resistance is 89.9 Ω inrush, 770 Ω holding at 68 °F (20 °C) — these numbers help size the external suppression, especially for DC operation where the holding current is much lower than inrush. Heat dissipation runs 15...18.3 W continuous. That's warm, not hot, but if you're stacking coils in a closed panel, add a little ventilation clearance. That's solid for frequent cycling like conveyor or pump control. Opening time is 60 ms, closing time 50 ms. That's typical for a large TeSys coil — not lightning fast, but consistent for interlocking sequences.","metaTitle":"Square D LX9FK931 TeSys Coil, 220-230V AC/DC, Obsolete","metaDescription":"Obsolete Square D LX9FK931 TeSys contactor coil, 220-230V AC/DC. 60ms opening, 50ms closing.
