Phoenix Contact QUINT-PS-1AC-24DC-10 Industrial Network Interface for QUINT Systems

Phoenix Contact QUINT-PS-1AC-24DC-10: Industrial Data Link Power for Smart Factory Networks

The Phoenix Contact QUINT-PS-1AC-24DC-10 is a high-performance 24VDC/10A DIN rail power supply engineered for the demanding data and power infrastructure of modern industrial networks. As a cornerstone of the QUINT Series, this unit delivers stable, conditioned DC power to every node in the automation chain — from field-level sensors and actuators through PLC controllers, remote I/O modules, HMI panels, SCADA gateways, and edge computing devices. In smart factory environments where millisecond-level communication latency and uninterrupted data flow are non-negotiable, the QUINT-PS-1AC-24DC-10 provides the electrical foundation that keeps the entire industrial data link operational.

Connected Automation Data Flow

In a fully integrated smart factory, the QUINT-PS-1AC-24DC-10 sits at the heart of the power distribution layer, energizing every device that participates in the industrial data flow. Consider a typical production line architecture: a Phoenix Contact AXC F 2152 AXC-series PLC controller orchestrates machine logic and communicates over PROFINET to a managed FL SWITCH 2008 industrial Ethernet switch, which distributes real-time process data across the network backbone. The QUINT-PS-1AC-24DC-10 supplies clean, regulated 24 VDC to both the PLC rack and the switch, ensuring that network jitter caused by power fluctuation is eliminated at the source.

Downstream, Phoenix Contact Axioline F remote I/O modules collect digital and analog signals from field instruments — pressure transmitters, flow sensors, temperature probes — and relay that data upstream via EtherNet/IP or PROFINET. Each I/O station is powered by a dedicated QUINT-PS-1AC-24DC-10 or a companion QUINT-PS/1AC/24DC/5 unit for lighter loads, maintaining voltage stability even during inrush events caused by simultaneous actuator switching. The built-in SFB (Static Boost Function) of the QUINT series delivers up to 200% rated current for 12 ms, ensuring that contactors and solenoid valves connected to the same bus do not cause voltage dips that could reset communication modules.

At the HMI layer, Phoenix Contact TP 3057T touch panels and third-party SCADA workstations receive process visualization data through OPC UA or Modbus TCP, with the QUINT-PS-1AC-24DC-10 providing the stable power rail that prevents display resets during peak load cycles. Protocol conversion between legacy PROFIBUS DP field devices and the modern PROFINET backbone is handled by a Phoenix Contact GW PB DP/PN gateway module — itself powered by the QUINT series — bridging older instrumentation into the unified data network without requiring hardware replacement.

For drive and motion control segments, Phoenix Contact CONTACTRON motor management relays and third-party variable frequency drives (VFDs) draw their control-circuit power from the QUINT-PS-1AC-24DC-10, while encoder feedback and speed reference signals travel over CANopen or DeviceNet to the PLC. The power supply’s signaling contact output connects directly to the PLC’s digital input, enabling the controller to detect power supply faults in real time and trigger alarm sequences in the SCADA system before a process upset occurs. Edge computing nodes — such as the Phoenix Contact PLCnext Control AXC F 3152 — aggregate data from multiple network segments and push analytics to cloud MES/ERP platforms, all sustained by the reliable DC bus that the QUINT-PS-1AC-24DC-10 maintains.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial digitalization is the coexistence of multiple communication protocols across different generations of equipment. A plant may simultaneously operate PROFIBUS DP legacy sensors, PROFINET-enabled new PLCs, Modbus RTU instruments, and IO-Link smart sensors — each speaking a different language and historically forming isolated data islands. The QUINT-PS-1AC-24DC-10 addresses this challenge not by converting protocols itself, but by providing the stable, noise-free power environment that protocol gateways and communication modules require to operate reliably at their rated performance.

Voltage ripple and transient spikes on the DC bus are a leading cause of communication module resets, CRC errors on serial links, and dropped Ethernet frames — all of which manifest as intermittent data gaps in SCADA historian databases and false alarms in DCS systems. The QUINT series’ active power factor correction (PFC) and output capacitor bank suppress these disturbances, delivering a clean 24 VDC rail that allows PROFIBUS repeaters, Modbus gateways, and industrial Ethernet switches to maintain their communication cycles without interruption.

Remote monitoring and diagnostics are enabled through the QUINT-PS-1AC-24DC-10’s potential-free signal contact, which can be wired to a PLC input or a remote I/O module to transmit power supply status to the SCADA system. Maintenance teams can monitor DC output voltage, load current, and fault states from the control room, enabling predictive maintenance scheduling before a power supply failure causes unplanned downtime. This transparency extends to system expansion: when new production cells are added, additional QUINT-PS-1AC-24DC-10 units can be paralleled using the Phoenix Contact QUINT-DIODE/40AC/2X20/1X40 redundancy module, ensuring that the expanded network segment inherits the same power quality and monitoring capability as the existing infrastructure.

Every unit shipped undergoes full-load burn-in testing and output voltage calibration before dispatch. Stock is maintained for immediate shipment, supporting both urgent replacement orders and planned project rollouts. All units carry a 12-month warranty covering manufacturing defects and component failures under normal operating conditions.

Industrial Connectivity FAQ

Q1: Does the QUINT-PS-1AC-24DC-10 support integration with PROFINET or EtherNet/IP networks?
The QUINT-PS-1AC-24DC-10 does not itself act as a PROFINET or EtherNet/IP device node, but it powers all devices on those networks — PLCs, switches, I/O modules, and gateways — with a stable 24 VDC rail. Its signal contact output can be wired to a PLC digital input, making power supply status visible within the PROFINET or EtherNet/IP controller’s diagnostic data. For direct network integration, pair it with a Phoenix Contact QUINT UPS module or a compatible power monitoring gateway.

Q2: How does the QUINT-PS-1AC-24DC-10 contribute to network stability and reduced communication latency?
Power supply instability is a primary cause of communication retries and increased effective latency on industrial Ethernet and fieldbus networks. The QUINT-PS-1AC-24DC-10’s regulated output with less than 1% ripple and its SFB inrush handling prevent voltage dips that would cause communication ASICs to enter error recovery states. By maintaining a clean DC bus, the unit ensures that managed switches, PLC CPUs, and gateway modules operate within their specified timing parameters, keeping cycle times deterministic.

Q3: Can multiple QUINT-PS-1AC-24DC-10 units be used in a redundant power configuration for critical SCADA or safety systems?
Yes. Phoenix Contact’s QUINT series is designed for redundant parallel operation using the QUINT-DIODE redundancy module. Two QUINT-PS-1AC-24DC-10 units can be connected in a 1+1 redundant configuration, with the diode module preventing reverse current flow between supplies. This architecture is commonly used for SCADA servers, safety PLC racks, and critical communication infrastructure where power supply failure cannot be tolerated. The signal contacts of both units can be monitored independently by the PLC for predictive fault detection.

Q4: What is covered under the 12-month warranty, and how is the unit tested before shipment?
The 12-month warranty covers all manufacturing defects, component failures, and output specification deviations under normal operating conditions as defined in the Phoenix Contact datasheet. Prior to shipment, each unit undergoes full-load output testing, input voltage range verification across the 85–264 VAC wide-range input, and signal contact function verification. Units that do not meet factory specifications are quarantined and not dispatched. Warranty claims are processed with replacement unit dispatch within standard lead times; contact plc.sales@zyplc.com for RMA procedures.
