📋 Core Electrical Specifications

📌 Structure & Caratteristiche

1. Elevata capacità di carico: 30Una corrente elevata, used for PLC output current amplification, tifosi, riscaldatori, solenoid valves and other inductive/resistive loads; widely applied in HVAC and industrial cabinets.
2. Plug-in design: Relay body can be pulled out from the base for easy maintenance and replacement; Matching base model: RPZF2.
3. Nessun indicatore LED: RPF2BBD without coil LED indicator; LED version: RPF2BED.
4. Compact housing, built-in DIN rail latch + panel mounting holes, dual mounting compatible.
5. Tipo senza blocco; contacts reset when coil de-energized.

🧰 Typical Application Scenarios

HVAC: 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 & Note di installazione

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. Per carichi induttivi (motori, bobine del contattore), 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: 24VCC, nessun LED

RPF2BED: 24VCC, con LED

RPF2BB7: 24VAC coil version

📦 Imballaggio

Imballaggio standard: 10 pezzi/scatola

Schneider RPF2BBD (2CO 30A, DC24V, No LED) Scenari applicativi

Core positioning: Plug-in high-power relay for PLC output amplification, 2contatti CO, 24VDC coil, max 30A (with gap), derated to 25A when side-by-side installed. Base RPZF2, Guida DIN / panel dual mounting, wide temperature range -40~+55℃, suitable for high-power load switching inside industrial cabinets.

1. HVAC & Building Air Conditioning (Applicazione più comune)
2. Central air handling units (UTA): 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 & ventilatori di scarico, DO point amplification for building BA systems

Vantaggi: 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. Macchine per l'imballaggio, linee di trasporto, attrezzature di assemblaggio: Control of heavy-duty conveyor belts, drying heating tubes and large solenoid valve banks
5. Control cabinets for air compressors & refrigeratori: Ventole di raffreddamento, drain pumps and heater on/off
6. Hydraulic/pneumatic stations: Auxiliary control of high-current solenoid directional valves and hydraulic pumps
7. Automazione degli edifici
8. Building distribution panels: High-power lighting circuits, ventilatori di scarico, sewage pumps and fire supply air fans
9. UPS machine room power cabinets: Tifosi, heaters and dehumidifier control
10. Commercial equipment control cabinets: Commercial ovens, drying equipment and high-power resistive heating loads
11. Nuova energia & 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. Attrezzature speciali (Wide Temperature Advantage)
15. Onboard / apparecchiature mobili, 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 & Suggerimenti per l'applicazione (Scenario Reminders)

1. Load types: Resistive loads preferred. For inductive loads such as motors and contactor coils, soppressione dei picchi (RC snubber / diodo / varistor) deve essere montato; 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. 2CO (DPDT) caratteristica: One contact set for main power circuit, the other for passive status feedback. This is the key advantage over RPF2ABD (2NO), 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. Montaggio su base: 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
