Product Details

QUINT-PS/1AC/24DC/5 2866750 Product Description

The Phoenix Contact QUINT-PS/1AC/24DC/5 (2866750) is engineered as a foundational power layer component within the QUINT control architecture. Its role extends far beyond simple AC-to-DC conversion — it actively participates in system health management, load protection, and signal integrity across every layer of an industrial automation platform.

At the control layer, this PSU directly powers Phoenix Contact ILC 150 ETH 2TX or AXC F 2152 PLCs, ensuring stable 24 VDC bus voltage under dynamic load conditions. The SFB (Selective Fuse Breaking) technology delivers up to 200% rated current for 12 milliseconds, enabling downstream miniature circuit breakers to trip selectively without collapsing the entire bus — a critical feature in multi-branch control cabinet designs.

At the I/O layer, the QUINT-PS/1AC/24DC/5 supplies power to Phoenix Contact Axioline F or Inline I/O modules, including digital input/output modules such as the AXL F DI8/1 DO8/1 1H and analog modules like the AXL F AI4 I 1H. Stable 24 VDC supply is essential for accurate 4–20 mA signal transmission and 0–10 VDC analog reference integrity across field instruments.

At the communication layer, the PSU supports uninterrupted operation of Phoenix Contact FL SWITCH 1008 or FL SWITCH 2008 industrial Ethernet managed switches, which handle PROFINET, EtherNet/IP, and Modbus TCP traffic between PLCs, remote I/O stations, and SCADA systems. Power quality directly affects network latency and packet loss rates in time-sensitive automation networks.

At the HMI layer, the QUINT-PS/1AC/24DC/5 provides clean 24 VDC to Phoenix Contact TP 3057T or Weintek cMT series operator panels. HMI panels are particularly sensitive to voltage ripple and transient dips; the QUINT's active power boost and output capacitor bank ensure display stability during motor start-up surges on shared power rails.

At the protection and redundancy layer, the QUINT-PS/1AC/24DC/5 is frequently paired with the Phoenix Contact QUINT-DIODE/40AC/2X20/1X40 redundancy module, enabling dual-PSU hot-standby configurations. This architecture eliminates single points of failure on the 24 VDC bus, meeting SIL 2 and IEC 62061 requirements for safety-critical applications in petrochemical and energy sectors.

At the signal isolation layer, downstream Phoenix Contact MCR-SL-S-U-4-U signal conditioners and MINI MCR-SL-UI-UI-NC isolation amplifiers rely on stable PSU output to maintain galvanic isolation between field sensors and control system inputs. Voltage fluctuations at the PSU level propagate directly into measurement accuracy errors at the signal conditioning stage.

At the terminal and wiring layer, Phoenix Contact PTFIX 6/18X2,5-NS35A distribution terminal blocks and UK 5 N series feed-through terminals are used to distribute the 24 VDC bus from the QUINT PSU output to multiple sub-circuits within the control cabinet. Proper bus bar design and terminal block selection ensure current derating compliance at elevated ambient temperatures.

At the maintenance and diagnostics layer, the DC OK relay contact output of the QUINT-PS/1AC/24DC/5 connects directly to a PLC digital input, enabling real-time PSU health monitoring via the SCADA system. Engineers can configure alarm thresholds, log PSU fault events, and trigger preventive maintenance workflows without physical inspection of the control cabinet — reducing mean time to repair (MTTR) in remote or hazardous installations.

Manufacturing & Discrete Automation: In automotive body shop welding lines and semiconductor wafer handling systems, the QUINT-PS/1AC/24DC/5 powers distributed I/O nodes and servo drive control circuits. Its SFB technology prevents nuisance tripping during robot arm acceleration cycles, maintaining production throughput and reducing unplanned downtime.

Power & Energy: In substation automation and grid protection relay panels, the QUINT PSU supplies 24 VDC to IEC 61850-compliant protection relays, RTUs, and communication gateways. Its wide input voltage range (85–264 VAC) accommodates fluctuating utility supply quality in remote substations, while ATEX Zone 2 certification permits installation in gas-hazardous environments adjacent to switchgear rooms.

Petrochemical & Process Control: In DCS-based process control systems for refinery distillation columns and reactor temperature control loops, the QUINT-PS/1AC/24DC/5 provides the stable power foundation for Phoenix Contact Inline or Axioline remote I/O stations connected via PROFIBUS DP or PROFINET. Redundant PSU configurations using the QUINT-DIODE module ensure continuous process operation during scheduled maintenance windows.

Water Treatment & Utilities: In SCADA-controlled pump stations and water treatment plant MCC panels, the QUINT PSU powers PLC racks, flow transmitter signal conditioners, and Ethernet switches. Its -25 °C cold-start capability ensures reliable operation in outdoor kiosks and unheated pump houses during winter months.

Mining & Metallurgy: In conveyor belt drive control panels and ore processing plant automation cabinets, the QUINT-PS/1AC/24DC/5 withstands high vibration and dust-laden environments. Its compact DIN-rail form factor allows integration into space-constrained junction boxes at remote conveyor transfer points.

Marine & Shipboard Systems: With DNV and GL type approval, the QUINT-PS/1AC/24DC/5 is certified for shipboard automation panels controlling ballast water management systems, engine room monitoring, and cargo handling automation. Its wide temperature range and vibration tolerance meet Lloyd's Register and Bureau Veritas installation requirements.

Q1: Is the QUINT-PS/1AC/24DC/5 2866750 compatible with Phoenix Contact Axioline F and Inline I/O systems for mixed-architecture control cabinets? Yes. The QUINT-PS/1AC/24DC/5 delivers a stable 24 VDC bus fully compatible with both Phoenix Contact Axioline F (AXL) and Inline (IB IL) I/O families. The adjustable output voltage (18–29.5 VDC) allows fine-tuning to compensate for cable voltage drop in extended DIN-rail installations. The DC OK relay contact integrates directly with PLC digital inputs for continuous power quality monitoring across mixed I/O architectures. No additional power conditioning is required for standard analog or digital I/O modules within the same cabinet.

Q2: How does the SFB technology affect downstream circuit breaker coordination and overall cabinet protection design? The SFB (Selective Fuse Breaking) technology in the QUINT-PS/1AC/24DC/5 provides up to 200% rated output current (10 A) for 12 milliseconds during fault conditions. This current pulse is sufficient to trip standard B- or C-curve miniature circuit breakers (MCBs) on individual branch circuits without collapsing the main 24 VDC bus. This enables selective protection coordination — only the faulted branch trips while all other circuits remain powered. For cabinet designs with 4–8 branch circuits, this eliminates the need for additional electronic circuit breakers, reducing BOM cost and panel space. Engineers should verify MCB trip curves against the QUINT's boost current profile during the protection coordination study phase.
