Phoenix Contact QUINT-PS/100-240AC/24DC/10 2938604 Industrial Network Power Supply

Phoenix Contact QUINT-PS/100-240AC/24DC/10 2938604: Industrial Power Backbone for Smart Factory Data Links

In modern smart manufacturing environments, stable and reliable DC power is not merely a utility — it is the foundation upon which every data link, every protocol exchange, and every real-time control decision depends. The Phoenix Contact QUINT-PS/100-240AC/24DC/10 (Part No. 2938604) is a high-performance DIN-rail mounted power supply from Phoenix Contact’s renowned QUINT-PS Series, engineered to deliver a regulated 24VDC / 10A output from a wide-range AC input of 100–240VAC. Designed for demanding industrial environments, this unit provides the clean, stable power that field devices, communication gateways, and control systems require to maintain uninterrupted data flow across the entire automation network.

As industrial sites evolve toward IIoT-driven architectures, the power supply is no longer a passive component. The QUINT-PS/100-240AC/24DC/10 integrates active monitoring capabilities, including SFB (Selective Fuse Breaking) technology and static boost function, which ensure that downstream devices — from Siemens S7-1200 / S7-1500 PLCs and Beckhoff CX series controllers to Phoenix Contact FL SWITCH managed industrial Ethernet switches — receive consistent voltage even during peak load transients. This is critical when communication modules such as the Phoenix Contact FL COMSERVER or PROFIBUS/PROFINET gateway modules are handling high-frequency protocol conversion tasks between field-level PROFIBUS DP devices and Ethernet-based SCADA systems.

Connected Automation Data Flow

The role of the QUINT-PS/100-240AC/24DC/10 becomes most apparent when tracing the complete data flow of a smart factory automation chain. At the field level, sensors — such as Phoenix Contact MACX analog signal conditioners and third-party 4–20mA transmitters — feed process values into remote I/O modules like the Phoenix Contact Inline IL series or Axioline F AXL F BK PN bus coupler nodes. These I/O stations are powered directly from the 24VDC rail supplied by the QUINT-PS unit, ensuring that signal integrity is maintained from the very point of acquisition.

Data collected at the I/O level is transmitted upstream via PROFINET or EtherNet/IP to the PLC controller — typically a Siemens S7-1500 CPU 1515 or an Allen-Bradley CompactLogix L33ER — where logic processing and real-time control decisions are executed. The managed industrial Ethernet switch, such as the Phoenix Contact FL SWITCH 2008, sits at the network core of this cabinet, routing data between the PLC, the QUINT-PS-powered communication modules, and the plant-level SCADA server. The QUINT-PS/100-240AC/24DC/10 powers this entire switch fabric without voltage sag, even when multiple ports are simultaneously handling high-bandwidth PROFINET cyclic data and acyclic diagnostic traffic.

For legacy field devices communicating over PROFIBUS DP or Modbus RTU, a Phoenix Contact FL COMSERVER UNI 232/422/485 serial gateway or a Helmholz NET2PRO PROFIBUS/PROFINET coupler bridges the protocol gap, converting serial frames into Ethernet packets that the SCADA system can process. The QUINT-PS unit powers these gateway devices reliably, ensuring that protocol conversion latency remains within the sub-millisecond range required for real-time alarm propagation and remote diagnostics. At the HMI layer, Siemens KTP700 Basic or Weintek MT8071iE panels draw their 24VDC supply from the same QUINT-PS rail, displaying live process data sourced from the PLC and SCADA system. The QUINT-PS’s active current limiting and SFB technology ensure that an HMI panel fault or short circuit does not cascade into a full system shutdown, protecting the integrity of the entire data chain.

At the edge computing layer, an industrial edge gateway — such as the Siemens SIMATIC IPC127E or a Moxa UC-8112 ARM-based controller — aggregates data from multiple PLCs and SCADA nodes, applying local analytics before forwarding structured data to cloud platforms via MQTT or OPC-UA. The QUINT-PS/100-240AC/24DC/10 provides the stable 24VDC supply that these edge devices require for continuous, uninterrupted operation, even in environments with fluctuating grid quality.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is the coexistence of multiple communication protocols across different generations of equipment. A typical manufacturing plant may simultaneously operate PROFIBUS DP networks from legacy Siemens S5/S7-300 systems, Modbus RTU from older variable frequency drives such as the ABB ACS550 or Siemens MICROMASTER 440, and modern PROFINET / EtherNet/IP networks from newer PLC installations. Without a reliable power backbone, protocol gateways and communication modules cannot maintain the stable operation needed to bridge these isolated data islands.

The Phoenix Contact QUINT-PS/100-240AC/24DC/10 directly addresses this challenge by providing a power supply that actively compensates for load changes, ensuring that communication gateways, managed switches, and remote I/O stations remain online during network reconfiguration events, firmware updates, or peak production loads. Its static boost function delivers up to 15A for 5 seconds, allowing downstream devices to start up simultaneously without causing voltage collapse — a common failure mode in undersized power supplies that leads to intermittent communication dropouts and false alarms in SCADA systems.

For production line transparency, the QUINT-PS supports integration with Phoenix Contact PROFICLOUD and third-party SCADA platforms such as Wonderware InTouch or Ignition by Inductive Automation, where power supply status can be monitored as a process variable alongside temperature, pressure, and flow data. This enables maintenance teams to detect early signs of power degradation — such as output voltage drift or increased output current draw — before they result in unplanned downtime. Remote diagnostics via the SCADA system allow engineers to assess power supply health from the control room, reducing the need for physical inspection of remote field cabinets.

System expansion is equally straightforward: additional QUINT-PS units can be connected in parallel using the Phoenix Contact QUINT-DIODE/40AC/2X20/1X40 redundancy module, creating a redundant 24VDC power architecture that eliminates single points of failure in critical automation networks. This scalability makes the QUINT-PS/100-240AC/24DC/10 a long-term investment for factories planning phased IIoT upgrades.

Industrial Connectivity FAQ

Q1: Does the QUINT-PS/100-240AC/24DC/10 support PROFINET or EtherNet/IP network monitoring?
The QUINT-PS/100-240AC/24DC/10 itself does not have a built-in Ethernet port for direct PROFINET integration; however, it can be paired with the Phoenix Contact QUINT-PS/1AC/24DC/10/CO variant or monitored via external current/voltage transducers connected to a PROFINET-capable I/O module. Its signaling contact output can be wired to a PLC digital input for alarm integration into SCADA and HMI systems.

Q2: What is the communication latency impact if the power supply voltage drops below 24VDC?
Industrial communication modules, particularly PROFINET devices operating in IRT (Isochronous Real-Time) mode, are highly sensitive to supply voltage variations. A voltage drop below 18VDC will typically cause PROFINET slaves to drop off the network, resulting in communication timeouts and PLC fault states. The QUINT-PS’s SFB technology and active voltage regulation maintain output within ±1% of setpoint, ensuring that communication latency remains stable and within the sub-millisecond range required for real-time control.

Q3: Can this power supply be used in hazardous area (ATEX Zone 2) installations?
Yes. The Phoenix Contact QUINT-PS/100-240AC/24DC/10 (2938604) carries ATEX Zone 2 certification, making it suitable for use in industrial environments where explosive atmospheres may occasionally be present. It must be installed in a suitable enclosure rated for the specific zone classification, and all wiring must comply with local ATEX installation standards.

Q4: What warranty and pre-shipment testing does this unit include?
Every Phoenix Contact QUINT-PS/100-240AC/24DC/10 (2938604) supplied by ZYPLC is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes output voltage verification, load regulation testing, and SFB function verification to confirm full operational compliance with Phoenix Contact factory specifications. Units are shipped in original or equivalent protective packaging to prevent transit damage.
