2320157 QUINT-DIODE12-24DC2X201X40 Phoenix Contact DIN Rail diode Module Input

Product Details

The Quint-Diode 12-24DC2X201X40 is a QUINT series rail-mounted redundant module that uses high-power Schottky diodes to provide true decoupling and redundancy protection for two 24V power supplies. When one of the power sources or cables fails, the load side can still obtain 24V power supply without disturbance, minimizing the risk of system shutdown. The module is equipped with LED status indication, alarm contacts and a 20A current capacity, making it the preferred choice for high availability applications such as process control, data centers, packaging and logistics equipment.

Core Features:

100% redundancy decoupling: Schottky solution, reduced forward voltage, low power consumption, and no need for additional heat dissipation
High power density: Single channel 20A, total output 40A, width only 35mm, saving cabinet space
Visual diagnosis: The green LED indicates the status of each input channel in real time, and the red LED indicates faults
Alarm contacts: 1 set of floating relay contacts (30V / 1A), suitable for PLC or light/buzzer
Wide operating temperature range: -25 °C... At +70 °C, it remains fully loaded without derating and remains stable even in extreme conditions
Easy installation: Standard DIN rail snap-on, with a 50mm heat dissipation space at the top and bottom
Complete certifications: CE, UKCA, UL, ATEX/IECEx Ex nA IIC T4 Gc, suitable for II 3G explosion risk areas

Typical applications

Process industry: Dual power supply redundancy for DCS/PLC, chemical plants, oil and gas platforms, and pharmaceutical clean rooms
Data center: Decoupling of dual 24VDC busbars in server cabinets ensures zero interruption during UPS switching
Logistics sorting: High-speed stacker cranes, shuttle vehicles, AGV charging stations, power redundancy with zero downtime
Food and beverage: Filling lines, labeling machines, robot workstations, reducing scrapping caused by power failures
Rail transit: Signal control cabinets, turnstiles, PIS systems, in compliance with the temperature and vibration requirements of EN 50155
