Problem: Your Modicon Premium Line Needs a Reliable Output Module
Downtime on a Modicon Premium system often traces back to a failed discrete output card. The TSXDSY08T2 solves that problem with eight transistor outputs that switch 24 V DC loads quickly and cleanly. This Schneider Electric module belongs to the Modicon Premium series and uses source (PNP) wiring, which many machine builders prefer for sensor-driven control panels.
What the TSXDSY08T2 Delivers
Each of the eight outputs handles up to 0.5 A per channel. That current rating covers small relays, indicator lamps, and compact solenoid valves without an intermediate relay. The module responds in 0.5 ms typical, so high-speed sorting and packaging tasks keep pace with the machine cycle. A single slot houses the entire card, which preserves rack space for other I/O.

Solving Downtime with Smart Diagnostics
A shorted solenoid or miswired lamp can destroy an output card. The TSXDSY08T2 includes electronic overload and short-circuit protection that trips automatically and recovers on reactivation. Maintenance teams spend less time tracing blown fuses and more time restoring production. The channel-to-bus isolation of 1500 V AC also shields the backplane from field transients, which extends the life of the entire rack.
Where This Module Fits
Packaging and Labeling Lines
High-speed label applicators rely on fast transistor outputs. The 0.5 ms response time keeps print-and-apply heads synchronized with conveyor speed, reducing mislabeled product and rework.
Material Handling and Sorting
Sorting gates and diverter arms need repeated switching. With 0.5 A per channel and PNP sourcing, the TSXDSY08T2 drives pneumatic solenoids directly, simplifying panel wiring and cutting component count.
Replacement and Upgrade Path
Because Schneider has discontinued this module, engineers often face a choice: redesign the I/O or find a direct replacement. Keeping a spare TSXDSY08T2 on the shelf avoids a full rack redesign and protects the existing PLC program. SpareTechPLC helps buyers verify availability before committing to a costly migration.
Installation and Setup
The module occupies one slot in a Modicon Premium rack. Field supply is 24 V DC, while the backplane draws 5 V DC at 55 mA. Power consumption follows 1.0 W plus 0.75 W multiplied by the number of active outputs and current per module. Mount the rack in a cabinet that maintains IP20 protection, and keep the card away from conductive dust and moisture. Follow Schneider’s wiring diagrams for PNP sourcing to avoid reverse-polarity damage.
Maintenance and Reliability
Inspect terminal connections periodically for looseness or corrosion. Check that output loads stay within 0.5 A per channel. The electronic protection resets after a fault clears, but repeated trips point to a failing field device. Keep spare modules in anti-static packaging and store them in a dry environment. Because lifecycle status is discontinued, confirm current availability with SpareTechPLC before ordering.
Compatibility and Integration
The TSXDSY08T2 works inside Modicon Premium racks and communicates through the backplane. It pairs with standard 24 V DC field devices using PNP wiring. Verify that your existing rack and processor support this module before purchase, since discontinued status may affect firmware or rack compatibility.
Frequently Asked Questions
Is the TSXDSY08T2 still in production?
No. Schneider Electric has discontinued this module. SpareTechPLC can confirm current stock and suggest alternatives if needed.
Can I use it with sinking (NPN) sensors?
No. This is a source (PNP) output module. Match it with PNP field devices or use interface relays.
What happens during a short circuit?
The module trips electronically and recovers automatically on reactivation. Fix the field wiring before resetting.
How much current can each channel handle?
Each of the eight channels supports up to 0.5 A at 24 V DC.
Does it require a separate power supply?
Yes. The field side needs 24 V DC, and the backplane supplies 5 V DC.
