LINTEC CX-2415PS Power Supply Module

Product Details

CX-2415PS Product Description

The LINTEC CX-2415PS is a dedicated rack-mount power supply module engineered for the LINTEC CX-Series modular PLC platform. Designed to deliver stable, regulated DC power across the full CX-Series backplane, the CX-2415PS serves as the foundational energy layer in distributed and centralised control architectures. Its role extends beyond simple power conversion — it actively supports system-level consistency, module synchronisation, and long-term operational reliability across multi-rack deployments in demanding industrial environments.

In modern industrial automation, the power supply module is not a peripheral component — it is the architectural anchor of every control cabinet. The CX-2415PS is engineered with this principle at its core, providing clean, regulated output that sustains CPU processing integrity, I/O signal accuracy, and communication bus stability simultaneously. Whether deployed in a single-rack configuration or extended across a multi-rack CX-Series system, the CX-2415PS ensures that every downstream module — from digital I/O to analogue signal conditioners — operates within its specified electrical envelope.

The CX-2415PS is most effectively understood within the context of the complete LINTEC CX-Series control platform. In a fully integrated CX-Series architecture, the CX-2415PS powers the backplane that hosts the CX-CPU32 or CX-CPU64 central processing unit, which manages programme execution, task scheduling, and inter-module communication. The CPU module relies on the CX-2415PS to maintain a stable internal bus voltage — any ripple or transient on the supply rail directly affects scan cycle consistency and deterministic control response.

On the I/O layer, modules such as the CX-DI32 (32-channel digital input) and CX-DO32 (32-channel digital output) draw their operating power from the same backplane bus regulated by the CX-2415PS. Analogue modules including the CX-AI16 (16-channel analogue input, 4–20 mA / 0–10 V) are particularly sensitive to power quality — the CX-2415PS's low-ripple output ensures that analogue signal resolution is not compromised by power-side noise, which is critical in process control applications where measurement accuracy directly influences control loop performance.

For communication-intensive deployments, the CX-Series supports gateway modules such as the CX-PNIO (PROFINET I/O adapter) and CX-PBDP (PROFIBUS DP master/slave interface). These communication modules require stable, uninterrupted power to maintain cyclic data exchange with field devices, SCADA systems, and HMI panels. The CX-2415PS provides the electrical foundation that keeps these communication cycles deterministic and fault-free.

In redundant power architectures, the CX-2415PS is designed to operate in parallel with a secondary power supply module — typically a second CX-2415PS unit — using the CX-Series redundant power coupling module (CX-PSRM). This configuration eliminates the power supply as a single point of failure, which is a mandatory design requirement in high-availability applications such as power generation, water treatment, and continuous process manufacturing. The redundant pair provides automatic, bumpless switchover in the event of a primary supply fault, with no interruption to CPU operation or I/O scanning.

At the HMI and supervisory layer, operator panels connected via the CX-Series communication bus — including third-party HMI terminals running on PROFINET or Modbus TCP — depend on the CX-2415PS-powered CPU to maintain real-time data refresh. The stability of the power supply directly influences the responsiveness of the operator interface and the accuracy of alarm and event logging.

For cabinet-level power distribution, the CX-2415PS is typically fed from a DIN-rail mounted circuit breaker and EMC line filter, ensuring that upstream grid disturbances are attenuated before reaching the PLC backplane. In multi-rack systems, each rack is equipped with its own CX-2415PS, with inter-rack communication handled by the CX-RACK-EXT expansion cable, maintaining electrical isolation between racks while preserving data bus integrity.

Manufacturing & Discrete Automation: In automotive body-in-white lines, packaging machinery, and assembly automation, the CX-2415PS powers CX-Series racks that manage servo drive coordination, conveyor sequencing, and vision system integration. The module's robust overcurrent protection prevents cascade failures when high-inrush servo drives are powered up simultaneously during system initialisation.

Power Generation & Utilities: In turbine control panels and substation automation cabinets, the CX-2415PS supports redundant PLC architectures where continuous uptime is non-negotiable. Its wide AC input range (100–240 V) accommodates the variable grid conditions common in utility environments, and its thermal shutdown protection ensures safe operation in high-ambient-temperature switchgear rooms.

Petrochemical & Process Industries: In refinery DCS migration projects and chemical reactor control systems, the CX-2415PS provides the stable power foundation required for high-channel-count analogue I/O racks. Process engineers specify the CX-2415PS in redundant configurations to meet SIL-rated system availability requirements, with the redundant power module pair providing the electrical resilience demanded by functional safety standards.

Water & Wastewater Treatment: Municipal water treatment SCADA systems rely on CX-Series PLCs for pump sequencing, dosing control, and flow measurement. The CX-2415PS's IP20-rated construction and wide operating temperature range make it suitable for installation in outdoor-rated control enclosures, while its diagnostic output signal enables the SCADA system to monitor power supply health in real time.

Mining & Metallurgy: In ore processing plants and smelting facilities, the CX-2415PS powers CX-Series racks controlling conveyor drives, crusher sequencing, and furnace temperature regulation. The module's short-circuit protection is particularly valued in mining environments where cable insulation degradation can cause intermittent faults that would otherwise damage unprotected power supplies.

Marine & Shipboard Systems: For vessel automation and engine room control panels, the CX-2415PS's wide input voltage tolerance accommodates the frequency and voltage variations inherent in shipboard power generation systems, ensuring that PLC-controlled ballast, propulsion monitoring, and cargo handling systems remain operational under variable generator loading conditions.

Q1: Can the CX-2415PS support a fully loaded CX-BP16 backplane with mixed I/O and communication modules? Yes. The CX-2415PS is rated at 15 A / 360 W output, which is sufficient to power a fully populated CX-BP16 16-slot backplane with a combination of digital I/O, analogue I/O, and communication gateway modules. For systems approaching the maximum backplane load, NANKMOS recommends calculating the total module current draw using the CX-Series system design guide and, where the load exceeds 80% of rated capacity, deploying a second CX-2415PS in a redundant power configuration using the CX-PSRM coupling module. This approach both increases available power headroom and eliminates the power supply as a single point of failure.

Q2: Is the CX-2415PS compatible with CX-Series CPU modules requiring firmware version 3.x or later, and does it support the CX-Series diagnostic bus for remote power monitoring? The CX-2415PS is compatible with all CX-Series CPU modules across firmware generations, as the power supply interface is hardware-defined at the backplane connector level and is independent of CPU firmware version. The module includes a power status signal output that connects to the CX-Series internal diagnostic bus, enabling the CPU to monitor supply voltage, output current, and fault status in real time. This diagnostic data is accessible via the CX-Series programming environment and can be mapped to SCADA or HMI displays for remote power health monitoring — a feature particularly valued in unmanned or remotely supervised installations.

Q3: What is the warranty coverage for the CX-2415PS supplied by NANKMOS, and what pre-shipment testing is performed? All CX-2415PS units supplied by NANKMOS are covered by a 12-Month Warranty from the date of dispatch. Prior to shipment, each unit undergoes functional verification including input voltage range testing, output voltage and current regulation checks, and protection circuit activation tests (overcurrent, overvoltage, short-circuit). Units are supplied with original LINTEC packaging and documentation where available. NANKMOS maintains in-stock inventory of the CX-2415PS to support urgent project requirements, with standard lead times of 3–7 business days for international shipments.
