Schneider Electric TSXPSY2600 Modicon Premium Power Supply Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Schneider Electric TSXPSY2600 is a single-slot 24 V DC power supply module engineered for the Modicon Premium automation platform. Designed for installation directly into the dedicated slot 0 position of Modicon Premium TSX RKY main and expansion backplane racks, it converts a primary 24 V DC input into two regulated secondary DC outputs. Operating across a wide primary input range of 19.2 to 30 V DC with a 2 A rated input current, the unit delivers a high-capacity 3.6 A output at 5 V DC to supply internal rack communications and module logic, alongside a dedicated 0.6 A auxiliary output at 24 V DC for external sensors and field input circuits.
Power connections to the TSXPSY2600 are wired through a front-mounted removable screw terminal block, enabling fast hardware replacement during maintenance routines without disconnecting individual field wires. As a dedicated hardware power module, replacing a failed unit with a spare TSXPSY2600 does not require direct software parameter loading or firmware transfers, provided primary wiring polarity and module loading constraints are maintained. Engineering software such as PL7 Pro and Unity Pro or EcoStruxure Control Expert communicates with the controller rack host. ABC Industrial Parts provides tested replacement units to support facilities in maintaining their operational equipment.
Real-time operational feedback is available on the module front panel via three LED indicators labeled OK, ALARM, and 24V, while an integrated front-panel RESET pushbutton allows maintenance staff to execute a direct hardware reset of the PLC CPU and local rack modules. The host Modicon Premium CPU continuously monitors supply health through dedicated system bits like %S11. When internal component degradation or severe rack overloads interrupt secondary output voltages, component-level faults are not field-serviceable, and sourcing a fully tested replacement from ABC Industrial Parts offers a dependable path to restore system operation.

Programming and Configuration
The TSXPSY2600 functions as a core hardware element within the Modicon Premium hardware catalog. System structure and module placement are configured using PL7 Pro or Unity Pro (now EcoStruxure Control Expert) programming environments. Although the power supply module itself does not store user execution code or parameter files, its position in slot 0 must match the hardware configuration declared within the software project.
Diagnostic supervision of the power supply is built directly into the PLC memory architecture. The host CPU uses system status bits, including system bit %S11, to report power supply state and backplane fault status, allowing application programs to monitor power integrity across local and expansion racks.
Communication and System Integration
Engineered for direct integration into Modicon Premium TSX RKY backplane racks, the TSXPSY2600 occupies the dedicated slot 0 position to connect directly to the internal rack bus. From this position, it distributes 5 V DC logic power across the backplane to drive the local CPU, communication modules, and digital or analog I/O cards up to a combined maximum of 3.6 A.
In addition to internal rack power distribution, the module provides a separate auxiliary output supplying 24 V DC at up to 0.6 A via its front removable screw terminal block. This auxiliary supply can power external field devices such as sensors and input detection loops, separating field sensor power distribution from the main control cabinet supply line.
Diagnostics and Status Indication
Visual diagnostic indication on the TSXPSY2600 is handled by three status LEDs located on the front panel. These LEDs provide immediate feedback regarding primary supply presence, internal backplane voltage status, auxiliary 24 V DC output health, and rack overload conditions.
The front panel also features an integrated RESET pushbutton. Pressing this pushbutton triggers an immediate hardware reset of the Modicon Premium CPU and all expansion modules installed in the backplane rack, enabling technicians to clear hardware lockups directly at the module interface.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| OK | Green - Solid ON / OFF | Green ON: Normal operating state with primary and secondary output voltages within tolerance. OFF: Loss of primary supply voltage or internal power supply failure. |
| ALARM | Red - Solid ON / OFF | Red ON: Power supply overload, secondary short-circuit, internal module fault, or rack backplane fault condition. |
| 24V | Green - Solid ON / OFF | Green ON: Auxiliary 24 V DC sensor power output present and within limits. OFF: Auxiliary sensor output missing, shorted, or overloaded. |
Replacement and Spare Part Considerations
When installing a replacement TSXPSY2600 module, confirm that it is inserted into the designated slot 0 position of a compatible Modicon Premium TSX RKY rack. The removable screw terminal block simplifies the exchange by allowing wiring harnesses to be disconnected and reattached as a single assembly without removing individual wires.
Prior to powering the replacement unit, verify that total current consumption on the 5 V DC backplane bus does not exceed 3.6 A, and that auxiliary 24 V DC sensor loops do not exceed 0.6 A. Overcurrent conditions on either secondary supply line will illuminate the red ALARM LED and disable power output.
Schneider Electric officially discontinued the Modicon Premium product family in December 2018. For long-term control system planning, facilities considering a system upgrade can migrate to the Modicon M580 platform using BMXCPS2000 power supply modules.
Frequently Asked Questions
What primary input voltage is required for the TSXPSY2600?
The TSXPSY2600 operates on a nominal 24 V DC input with an acceptable operating range of 19.2 to 30 V DC. Rated input current is 2 A, and inrush current can reach up to 30 A.
What are the output power capacities of the TSXPSY2600?
The module provides two distinct outputs: a 5 V DC backplane output rated at 3.6 A for internal rack modules, and a 24 V DC auxiliary output rated at 0.6 A for field sensors.
Which slot position does the TSXPSY2600 occupy in a Modicon Premium rack?
The module requires a single slot and must be installed into the dedicated slot 0 position of Modicon Premium TSX RKY backplane racks.
What condition causes the red ALARM LED to illuminate?
The red ALARM LED turns solid ON when there is a power supply overload, a secondary short-circuit, an internal module failure, or a rack backplane fault.
What function does the front-panel RESET pushbutton perform?
Pressing the integrated front-panel RESET pushbutton forces a complete hardware reset of the Modicon Premium CPU and connected modules within the local rack.
Which software environments support hardware setups containing this module?
Modicon Premium control systems utilizing the TSXPSY2600 are configured using PL7 Pro or Unity Pro (EcoStruxure Control Expert) programming software.
