The LA4EM250FL2 is an electronic control module from the Schneider Electric TeSys F range, designed specifically to drive the LXEFL2502 coil. It handles control voltages from 100 to 250 V AC/DC, making it suitable for both AC and DC control circuits common in industrial panels. The module is rated for switching loads up to 2600 A in AC-1 duty (resistive load), which places it in the high-current contactor control space — think large motor starters, heating banks, or transformer primary switching where the inrush isn't the limiting factor.
The control circuit accepts 100...250 V AC/DC, with operational limits of 85...275 V AC/DC at 55 °C. Drop-out thresholds are clearly defined: 0...65 V AC and 0...51 V DC — important for ensuring the contactor drops out reliably on undervoltage. The built-in bidirectional peak limiting coil technology means you don't need external suppression for the coil drive; the module handles the inductive kick internally, which simplifies panel wiring and reduces component count. Input compatibility with PLC 24 V DC per IEC 61131-2 Type 2 means this module can be driven directly from a standard PLC output without an interposing relay. The off-state voltage threshold is 0...5 V, on-state is 11...30 V — so a 24 V PLC output is well within range. Heat dissipation runs 16...20 W at steady state, with inrush power peaking at 1300...2400 W (or 1100...2300 VA). That inrush spike matters for power supply sizing if you're driving multiple modules from the same 24 V DC bus.
Integration Notes
The module connects to the LXEFL2502 coil as a required companion device — they are a matched pair. Control circuit wiring uses a removable screw terminal block accepting 0.2...2.5 mm² wire (solid, flexible, or flexible with ferrule). Tightening torque is 0.5...0.6 N·m for the control terminals. Mounting is DIN-rail compatible within the TeSys F contactor footprint, so panel layout follows standard practices for this series.
