Schneider TSXPSI2010 Modicon Premium Atrium Power Supply Module

Product Overview

The TSXPSI2010 is a specialized 24 VDC power supply module engineered for the Modicon Premium and Atrium slot PLC platforms. Specifically designed for "Atrium slot PLC Unity" configurations, this module provides the critical voltage stabilization and current regulation required to power Atrium processors residing in PC-based automation slots. The TSXPSI2010 acts as a robust electrical interface, shielding sensitive PLC logic from the electrical noise and fluctuations inherent in industrial PC power buses. With a high inrush current tolerance and integrated short-circuit protection via a 2 A time-delay fuse, it ensures that the control system remains operational in demanding environments such as automotive assembly, material handling, and complex machine control.

Technical Configuration

The TSXPSI2010 hardware architecture is built for precision power delivery and system safety:

• Voltage Regulation: Operates on a nominal 24 VDC input with a wide tolerance band (19.2 V to 30 V), accommodating standard industrial battery or rectified power sources.

• Microbreak Immunity: Designed with internal capacitance to bridge voltage dips of up to 7 ms, preventing system resets during brief power interruptions or supply switching.

• Connectivity: Features specialized electrical interfaces including one female SUB-D 9 connector and one female SUB-D 3 connector dedicated to the supply voltage input.

• Protection Circuitry: Includes an internal 2 A time-delay fuse to protect against overcurrent and short-circuits, alongside high immunity to inrush currents (100 A at 25 deg C).

• Atrium Integration: Form-factored to integrate seamlessly with Atrium slot PLC architectures, providing the "Unity" compatible power layer for PC-integrated safety and control.

Technical Specifications

Technical FAQs

Is the TSXPSI2010 compatible with standard Modicon Premium RKY racks?

No, this specific model is designed for the Atrium slot PLC platform. Standard Modicon Premium racks typically use the TSXPSY series (e.g., TSXPSY2600). The TSXPSI2010 is intended for the PC-based slot-PLC versions of the Modicon architecture.

How does the module handle brief power losses?

The module has an immunity to microbreaks of up to 7 ms at 24 V. If the supply voltage drops for a duration shorter than this, the internal energy storage maintains the processor's operation without a system halt.

What type of cabling is required for the SUB-D 3 connector?

The SUB-D 3 connector is used for the primary 24 VDC supply input. It is critical to use properly shielded, twisted-pair cabling to minimize EMI and ensure that the "Unity" software diagnostics for power health remain accurate.

Engineering & Installation Guide

• Inrush Current Planning: When sizing your 24 VDC bulk power supply, account for the 100 A inrush current of the TSXPSI2010. While this spike lasts only milliseconds (3 A²s), a power supply with overly sensitive "electronic fuse" trip settings may fail to start.

• Thermal Environment: Ensure that the industrial PC or enclosure housing the Atrium slot PLC has adequate airflow. The TSXPSI2010 is rated for operation up to 60 deg C; however, if the PC's internal ambient temperature exceeds this due to high CPU load, the power supply module's lifespan may be reduced.

• Grounding and Shielding: The SUB-D connectors must be securely tightened to the chassis. The metal shell of the SUB-D connector provides the necessary path to ground for electromagnetic interference. A loose connector can lead to intermittent "I/O Fault" or "Power Supply Fault" LEDs on the Atrium processor.

• Fuse Maintenance: If the module fails to power up, check the internal 2 A time-delay fuse. Always replace it with an identical rating (IEC 1131-2 compliant) to maintain the safety certification and protective characteristics of the module.
