Introduction
Finding a reliable replacement for a discontinued I/O module can stall an entire production line. The TSXDEY16D3 from Schneider Electric belongs to the Modicon Premium series and delivers 16 discrete DC input points in a single slot. This module is now discontinued, so buyers must confirm availability before committing to a purchase. SpareTechPLC specializes in sourcing hard-to-find automation parts like this one.
What This Module Does
The TSXDEY16D3 accepts 48 V DC field signals across 16 points, arranged in two groups of eight. Each channel draws 7 mA at state 1. The module uses negative logic, meaning the input activates when tied to the negative reference. A typical response time of 4 ms keeps signal detection fast enough for most industrial control loops. With no onboard diagnostics, the module relies on external system monitoring for fault detection.
Key Technical Parameters

Comparison with Similar Input Modules
| Feature | TSXDEY16D3 | Typical 24 V DC Input Module |
|---|---|---|
| Voltage range | 48 V DC | 24 V DC |
| Channels | 16 (2 × 8) | 16 or 32 |
| Isolation | 1500 V AC | Varies by model |
| Diagnostics | Not available | Often available |
| Lifecycle | Discontinued | Varies |
This comparison highlights why the TSXDEY16D3 suits legacy systems already wired for 48 V DC field devices. Switching to a 24 V DC module would require rework of field wiring and power supplies.
Where It Fits in Your System
The 48 V DC input range makes this module useful in applications where higher field voltages reduce noise susceptibility over long cable runs. Common scenarios include:
- Legacy Modicon Premium racks that already use 48 V DC field devices and need a drop-in replacement.
- Material handling systems where 48 V DC sensors and switches are standard.
- Upgrade projects where replacing the entire I/O platform is not cost-effective.
Because the module is discontinued, buyers should treat it as a legacy spare rather than a long-term platform choice.
Installation and Setup
The TSXDEY16D3 occupies one slot in a Modicon Premium rack. It draws 80 mA from the 5 V DC backplane and requires a 48 V DC field supply. The IP20 rating means the module belongs inside a protected cabinet, away from dust and moisture. Follow Schneider Electric’s installation documentation for wiring and grounding. Do not attempt internal repairs or modifications.
Maintenance and Reliability
Since diagnostics are not available, periodic inspection of field wiring and terminal connections is essential. Check for loose connections, corrosion, and signs of overheating. Keep the cabinet environment within the limits specified by the rack manufacturer. Because the module is discontinued, maintaining a spare unit on the shelf reduces downtime risk. Contact SpareTechPLC to discuss current stock and replacement options.
Compatibility and Integration
The TSXDEY16D3 works within Modicon Premium racks and communicates through the backplane. It does not support standalone operation. Verify that your existing rack, power supply, and terminal blocks match the requirements of this module before ordering. The 1500 V AC channel-to-bus isolation protects the backplane from field transients, which helps preserve other modules in the same rack.
Selection Guide
Before purchasing the TSXDEY16D3, confirm the following:
- Your application uses 48 V DC field signals with negative logic.
- Your rack has an available slot and adequate 5 V DC backplane current.
- You accept the discontinued lifecycle status and have a plan for long-term support.
SpareTechPLC can help verify compatibility and availability. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Frequently Asked Questions
Is the TSXDEY16D3 still in production?
No, Schneider Electric has discontinued this module. Contact SpareTechPLC for current stock and replacement options.
Can I use this module with 24 V DC signals?
No. The TSXDEY16D3 is rated for 48 V DC field signals only. Using a lower voltage may prevent reliable input detection.
Does this module provide diagnostics?
No. Diagnostics are not available on this model. External monitoring is required for fault detection.
What is the power consumption?
Power consumption is 1.0 W plus 0.15 W for each channel used.
How many slots does it require?
The module occupies one slot in a Modicon Premium rack.
