📌 Structure & 特徴
- 高い耐荷重性: 30大電流, used for PLC output current amplification, ファン, ヒーター, solenoid valves and other inductive/resistive loads; widely applied in HVAC and industrial cabinets.
- Plug-in design: Relay body can be pulled out from the base for easy maintenance and replacement; Matching base model: RPZF2.
- No LED indicator: RPF2BBD without coil LED indicator; LED version: RPF2BED.
- Compact housing, built-in DIN rail latch + panel mounting holes, dual mounting compatible.
- Non-latching type; contacts reset when coil de-energized.
🧰 Typical Application Scenarios
空調設備: 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 & インストールに関する注意事項
- 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.
- 誘導負荷の場合 (モーター, 接触器コイル), surge suppression components are recommended in parallel to extend contact life.
- Base must be RPZF2, RXM small relay bases cannot be used interchangeably.
- Distinguish suffix codes:
RPF2BBD: 24VDC, no LED
RPF2BED: 24VDC, with LED
RPF2BB7: 24VAC coil version

📦 Packaging
Standard packing: 10 個/箱
Schneider RPF2BBD (2CO 30A, DC24V, No LED) アプリケーションシナリオ
コアの位置決め: Plug-in high-power relay for PLC output amplification, 2CO接点, 24VDCコイル, max 30A (with gap), derated to 25A when side-by-side installed. Base RPZF2, DINレール / panel dual mounting, wide temperature range -40~+55℃, suitable for high-power load switching inside industrial cabinets.
- 空調設備 & Building Air Conditioning (最も一般的なアプリケーション)
- Central air handling units (AHU): Control of fans, electric heating sections, humidifiers and condensate pumps
- Heat pump units & constant temperature/humidity control cabinets: Auxiliary compressor circuits, high-power actuating for water valves
- Fresh air purification units: Start/stop of large supply & 排気ファン, DO point amplification for building BA systems
利点: 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.
- Industrial Automation Control Cabinets
- 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.
- 包装機, コンベアライン, assembly equipment: Control of heavy-duty conveyor belts, drying heating tubes and large solenoid valve banks
- Control cabinets for air compressors & チラー: Cooling fans, drain pumps and heater on/off
- Hydraulic/pneumatic stations: Auxiliary control of high-current solenoid directional valves and hydraulic pumps
- ビルディングオートメーション
- Building distribution panels: High-power lighting circuits, 排気ファン, sewage pumps and fire supply air fans
- UPS machine room power cabinets: ファン, heaters and dehumidifier control
- Commercial equipment control cabinets: Commercial ovens, drying equipment and high-power resistive heating loads
- 新エネルギー & Energy Storage Auxiliary Systems
- Energy storage BMS cabinets: Switching of cooling fans, cabin heaters and dehumidification loads
- Auxiliary loads of small PV combiner boxes: Fans and anti-condensation heating circuits
- 特別装備 (Wide Temperature Advantage)
- Onboard / モバイル機器, construction machinery electrical cabinets: -40℃ cold start, withstand wide temperature shock
- Marine auxiliary machinery control cabinets (select with marine certifications): Cabin fans and pump loads
✅ Selection & Application Tips (Scenario Reminders)
- Load types: Resistive loads preferred. For inductive loads such as motors and contactor coils, サージ抑制 (RCスナバ / diode / varistor) must be fitted; otherwise contact service life will drop sharply.
- 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.
- 2CO (DPDT) feature: One contact set for main power circuit, the other for passive status feedback. This is the key advantage over RPF2ABD (2いいえ), ideal for automation systems requiring relay status acquisition.
- No LED: Suitable for cabinet interiors where visual coil status indication is not required. Choose RPF2BED if LED indicator is needed.
- ベース取り付け: 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
