Why This Module Still Matters for Your Modicon Premium System
The TSXDSY16T3 is a discontinued 16-point discrete output module from Schneider Electric’s Modicon Premium series. It delivers 24 V DC sinking (NPN) transistor outputs across two groups of eight channels. For plants still running Modicon Premium racks, this module often sits at the heart of machine control, packaging lines, and material handling systems. When one output card fails, the whole line can stop. That downtime costs far more than the module itself.
This is where a cost-analysis mindset pays off. Buying verified spare stock now is almost always cheaper than an emergency line stoppage. SpareTechPLC specializes in sourcing discontinued Schneider automation parts, so you can keep production running while planning a longer-term migration.
Key Specifications That Drive Your Cost Per Point
16 Channels in a Single Slot
With 16 outputs packed into one slot, the TSXDSY16T3 reduces rack space and wiring labor. Fewer modules mean lower cabinet cost and simpler maintenance. Each channel handles 0.5 A at 24 V DC — enough for relays, solenoids, and indicator lamps. If you currently use two 8-point cards, this module can cut your per-point hardware cost significantly.
Fast 1.2 ms Response Time
A 1.2 ms response time keeps high-speed sorting and pick-and-place tasks accurate. Slow outputs cause missed actuations and rejected product. Faster response means less scrap and better throughput — a direct saving on every shift.
Built-In Overload and Short-Circuit Protection
The module includes electronic overload and short-circuit protection with auto trip on reactivation. This feature protects wiring and downstream devices from damage. Fewer blown fuses and fewer replaced sensors lower your total maintenance spend.
Solid Isolation for Noisy Plants
Channel-to-bus isolation of 1500 V AC and isolation resistance above 10 MΩ at 500 V keep field noise away from the backplane. In welding or motor-heavy environments, this isolation prevents phantom signals that cause random machine stops.
Compact, Lightweight Footprint
At 140 × 35 × 80 mm and 0.15 kg, the module fits standard Premium racks with IP20 protection. Its light weight reduces shipping cost and makes field replacement quick.
Where the TSXDSY16T3 Earns Its Keep
Packaging and Palletizing Lines
Solenoid valves and pneumatic actuators run directly from these 24 V DC outputs. The 0.5 A per channel rating covers most valve pilots without extra relays. Removing relays cuts panel cost and failure points.
Material Handling and Conveyor Control
Conveyor diverters, brakes, and indicator stacks rely on fast, reliable switching. The 1.2 ms response time keeps product tracking accurate, which reduces jams and rework.
Legacy Machine Retrofits
When a Modicon Premium system is still productive, replacing a failed output card is far cheaper than a full PLC migration. Sourcing a verified TSXDSY16T3 extends asset life at a fraction of new-system cost.
Installation and Setup Notes
Mount the module in one Premium rack slot and confirm the backplane 5 V DC supply. The module draws 80 mA at 5 V DC from the bus. Field power comes from a 24 V DC supply. Keep output wiring separated from high-voltage cables to preserve the 1500 V AC isolation. Label the two groups of eight channels clearly so technicians can trace faults quickly.
Maintenance and Reliability Planning
Inspect terminal connections during scheduled shutdowns. Check for loose screws, heat discoloration, and dust buildup. Because the module auto-trips on overload, log any trip events — repeated trips point to a failing field device, not the card. Keeping one spare on the shelf is the cheapest insurance against unplanned downtime.
Compatibility and Integration
The TSXDSY16T3 works within Modicon Premium racks and connects to field devices through standard 24 V DC sinking wiring. It suits NPN sensors and loads that switch to ground. Confirm your existing wiring polarity before replacement, since sink and source modules are not interchangeable.
What to Verify Before You Buy
This module is discontinued, with lifecycle status last verified in September 2026. Before ordering, confirm your rack series, channel count, and output type. Check that your field devices accept sinking (NPN) outputs at 24 V DC. SpareTechPLC can help you verify availability and identify a suitable replacement path if stock is limited.
Frequently Asked Questions
Is the TSXDSY16T3 still in production?
No. Schneider Electric lists this module as discontinued. Availability depends on remaining stock and refurbished units. Contact SpareTechPLC to confirm current supply.
Can I replace an 8-point output card with this 16-point module?
Yes, if your rack has a free slot and your wiring supports two groups of eight outputs. You gain double the points in one slot, which lowers per-point cost.
What happens if an output short-circuits?
The module includes electronic overload and short-circuit protection. It trips automatically and reactivates after the fault clears, protecting the card and wiring.
Does this module work with sourcing (PNP) field devices?
No. The TSXDSY16T3 provides sinking (NPN) outputs. Use it with devices that switch to ground, or select a sourcing module instead.
How much power does the module draw?
It draws 80 mA at 5 V DC from the backplane. Total power consumption is 2.4 W plus 0.85 W per active output based on current.
