Product Overview
Phoenix Contact 2320034 is a high‑performance isolated QUINT POWER DC‑DC converter for industrial cabinet applications. It accepts wide‑range 24 V DC input and delivers stabilized 24 V DC output with full galvanic isolation between input and output sides. This unit supports voltage restoration for long cable runs, creates electrically separated power zones for sensitive automation hardware, and provides robust overload and short‑circuit protection via SFB technology. Conformal coating enhances reliability under dusty, chemically‑aggressive industrial conditions. Widely deployed for new cabinet builds as well as replacement spare for existing factory automation systems.
Series
QUINT POWER is Phoenix Contact’s premium power supply family for demanding industrial environments. The portfolio includes AC‑DC power supplies, DC‑DC converters and buffer modules. QUINT units feature power‑burst overload capability, SFB selective fuse breaking, preventive monitoring signals and conformal coating options, focusing on high‑availability power for PLC, DCS, drive and safety‑related control hardware.

Function
2320034 takes fluctuating 24 V DC supply from plant‑side power sources, performs isolated DC‑DC conversion and delivers tightly‑regulated 24 V DC to field‑side loads. It compensates voltage drop caused by long cable distances. Built‑in SFB technology trips downstream fuses selectively during short‑circuit events without collapsing the whole system bus. The DC‑OK relay transmits power‑healthy status signals to PLC/DCS for remote supervision. Conformal coating secures stable operation under dust, humidity and chemical vapors inside industrial control cabinets.
Purpose
Provide isolated, stabilized 24 V DC power for PLC, sensors, relays and automation I/O modules. Create electrically‑separated power domains, compensate long‑line voltage loss, and improve system availability. Used for new cabinet construction as well as spare‑part replacement for failed DC‑DC converters in existing installations.
Application Fields
Factory automation control cabinets, machine‑building equipment, process‑industry DCS and PLC systems, material‑handling lines, water‑wastewater treatment plants, marine auxiliary control systems, chemical‑plant cabinet power distribution projects.
