Phoenix Contact QUINT-DIODE-40 2938963 Redundancy Module

Engineered for mission-critical systems where power interruptions aren’t an option, this redundancy module ensures seamless power supply continuity through automatic switchover between dual sources. Commonly deployed in industrial automation, process control, and transportation infrastructure, it keeps operations running when grid stability falters.

For applications like automotive assembly lines or railway signaling systems, where a power hiccup could mean safety risks or production losses, this module becomes indispensable. We frequently pair it with Phoenix Contact’s QUINT-PS-10R power supplies and QUINT-ORP-4 redundancy modules in systems requiring N+1 redundancy. One plant manager reported maintaining full production throughput during a regional brownout that affected 80% of their facility’s conventional circuits.

What makes this module stand out is its passive diode architecture that eliminates single points of failure. The dual-path design (2×20 A) automatically balances load between sources while blocking reverse current – no configuration required. Unlike active switching systems, there’s zero transfer time since both sources remain connected. The rugged DIN-rail form factor survives harsh environments with 95% humidity at 25°C and resists vibration up to 15G shock. Certified for global deployment (UL, CE, ATEX), it integrates seamlessly with PLC control systems from Siemens, Allen Bradley, and Schneider.
