1. Model Differences & Opciones de reemplazo
2. LP1K0910BD: Misma calificación, incorporado 1 NO (Normalmente abierto) contacto auxiliar (most frequently confused model)
3. LP1K0901BD3: Spring-cage terminal variant (different wiring method)
4. LC1K0901M7: Misma calificación actual, AC220V AC coil version, cannot be directly interchanged
5. Alternativas domésticas: Chint NC1K, Delixi CJX2K miniature contactors; verify mounting dimensions and auxiliary contact configuration before replacement
6. Notas importantes

bobina de CC; do not connect directly to AC24V supply

DC coils generate back EMF when de-energized. Add a freewheeling diode if driven by PLC transistor outputs to protect the output channel

LA1K auxiliary contact blocks can be snapped on top to expand additional auxiliary contacts

LP1K0901BD (TeSys K, 3Pregunta 9A, CC 24 V, Built-in 1NC) Casos de aplicación

Ventajas principales: Bobina de 24V CC, directly driven by PLC transistor outputs; incorporado 1 NC contact for interlock and status feedback; sólo 45 mm de ancho, ideal for dense OEM control cabinets; AC-3 rating for 4kW @ 380V

Caso 1: Small Fan Control for AHU / Fresh Air Handling Units (Building BMS & climatización)

Carga: 380V three-phase centrifugal fans & ventiladores de escape (0.75~4kW)

Lógica de control: DDC/PLC transistor output directly energizes the LP1K0901BD coil; main contacts switch the fan power; the built-in 1 NC contact sends stop feedback to BMS (NC closes when the contactor drops out to report fan shutdown)

Matching components: MCB upstream + LR2K thermal overload relay for motor protection; multiple contactors installed side-by-side on DIN rail to save cabinet space

Beneficios: No AC hum from DC coils, suitable for quiet computer room & air-conditioning control cabinets; fully compatible with 24VDC building control buses

Caso 2: Segmented Conveyor Drives for Packaging & 3Automatización C (Alimento & Electronic OEM)

Carga: Sectional belt conveyors, small drum motors, alimentadores de material, agitator motors (≤4kW)

Lógica de control: PLC 24VDC outputs control jog or continuous operation; multiple LP1K0901BD units control individual conveyor sections; 1 NC contacts implement section interlock (next section cannot start if the upstream section is still running)

Condiciones de funcionamiento: Ciclismo frecuente (arriba a 3,600 operaciones/hora). 10 million mechanical cycles fit continuous production lines; IP20 protection meets clean cabinet requirements for food workshops

Recordatorios: Fit a freewheeling diode across the coil to suppress back EMF and prevent PLC transistor burnout

Caso 3: Small Pump Stations & Circulating Water Systems (Tratamiento de agua & Constant Temperature Tanks)

Carga: 380V circulation pumps, chemical dosing agitators, bombas de agua de refrigeración

Lógica de control: [text truncated in original draft]

10. Guía de selección rápida
11. Need RUN feedback (SIN contacto) → select 10 (LP1K0910BD)
12. Need STOP feedback (contacto NC) → select 01 (LP1K0901BD, tu modelo actual)
13. PLC transistor output: prefer BD3 (supresión de sobretensiones incorporada) to eliminate external diodes
14. Vibration-prone conveyor applications: choose spring-cage terminal suffix 3 (BD3)
