3. لا يوجد مؤشر LED: RPF2BBD without coil LED indicator; LED version: RPF2BED.
4. Compact housing, built-in DIN rail latch + panel mounting holes, dual mounting compatible.
5. Non-latching type; contacts reset when coil de-energized.

🧰 Typical Application Scenarios

التدفئة والتهوية وتكييف الهواء: Control of fans, electric heaters and water pumps

Industrial automation control cabinets: PLC output power expansion

Switching high-power circuits for air compressors, packaging machinery and conveyors

High-power load switches inside control cabinets

⚠️ Selection & ملاحظات التثبيت

1. Derating requirement: When multiple relays are mounted side-by-side tightly, rated contact current is derated to 25A; a 13mm gap between relays is required to reach full 30A rating.
2. للأحمال الحثية (المحركات, لفائف المقاولين), surge suppression components are recommended in parallel to extend contact life.
3. Base must be RPZF2, RXM small relay bases cannot be used interchangeably.
4. Distinguish suffix codes:

RPF2BBD: 24VDC, لا الصمام

RPF2BED: 24VDC, مع الصمام

RPF2BB7: 24VAC coil version

Schneider RPF2BBD (2CO 30A, تيار مستمر 24 فولت, No LED) سيناريوهات التطبيق

تحديد المواقع الأساسية: Plug-in high-power relay for PLC output amplification, 2CO contacts, 24لفائف VDC, max 30A (with gap), derated to 25A when side-by-side installed. Base RPZF2, السكك الحديدية الدين / panel dual mounting, wide temperature range -40~+55℃, suitable for high-power load switching inside industrial cabinets.

1. التدفئة والتهوية وتكييف الهواء & Building Air Conditioning (التطبيق الأكثر شيوعا)
2. Central air handling units (أهو): Control of fans, electric heating sections, humidifiers and condensate pumps
3. Heat pump units & constant temperature/humidity control cabinets: Auxiliary compressor circuits, high-power actuating for water valves
4. Fresh air purification units: Start/stop of large supply & exhaust fans, DO point amplification for building BA systems

المزايا: 24VDC coil matches DDC controllers; 2CO contacts can control main power circuit and feedback signal simultaneously. Wide temperature range suits machine rooms and outdoor cabinets.

2. Industrial Automation Control Cabinets
3. PLC digital output amplification: PLC DO points normally rated 0.5~2A. RPF2BBD drives 30A resistive/inductive loads and isolates strong/weak current to protect PLC modules. One set of 2CO contacts for main load, the other for passive status feedback to PLC DI.
4. ماكينات التعبئة والتغليف, conveyor lines, معدات التجميع: Control of heavy-duty conveyor belts, drying heating tubes and large solenoid valve banks
5. Control cabinets for air compressors & المبردات: Cooling fans, drain pumps and heater on/off
6. Hydraulic/pneumatic stations: Auxiliary control of high-current solenoid directional valves and hydraulic pumps
7. أتمتة البناء
8. Building distribution panels: High-power lighting circuits, exhaust fans, sewage pumps and fire supply air fans
9. UPS machine room power cabinets: المشجعين, heaters and dehumidifier control
10. Commercial equipment control cabinets: Commercial ovens, drying equipment and high-power resistive heating loads
11. الطاقة الجديدة & Energy Storage Auxiliary Systems
12. Energy storage BMS cabinets: Switching of cooling fans, cabin heaters and dehumidification loads
13. Auxiliary loads of small PV combiner boxes: Fans and anti-condensation heating circuits
14. معدات خاصة (Wide Temperature Advantage)
15. Onboard / mobile equipment, construction machinery electrical cabinets: -40℃ cold start, withstand wide temperature shock
16. Marine auxiliary machinery control cabinets (select with marine certifications): Cabin fans and pump loads

✅ Selection & Application Tips (Scenario Reminders)

1. Load types: Resistive loads preferred. For inductive loads such as motors and contactor coils, قمع الطفرة (RC snubber / الصمام الثنائي / varistor) must be fitted; otherwise contact service life will drop sharply.
2. Current derating: When multiple RPF relays are closely mounted side-by-side, use 25A as rated current; reserve ≥13mm gap between relays to achieve full 30A.
3. 2شركة (دي بي دي تي) ميزة: One contact set for main power circuit, the other for passive status feedback. This is the key advantage over RPF2ABD (2لا), ideal for automation systems requiring relay status acquisition.
4. No LED: Suitable for cabinet interiors where visual coil status indication is not required. Choose RPF2BED if LED indicator is needed.
5. تركيب القاعدة: RPZF2 base is mandatory; RXM small relay bases cannot be used. Plug-in design enables fast on-site replacement.

❌ Not Recommended Applications

Direct switching of main circuit for three-phase high-power motors (use contactors for motor main circuits; RPF only for auxiliary control)

Applications with extremely frequent switching cycles (limited contact life)

Loads exceeding 30A
