Schneider Electric TSXAEG4111 – Analog Input Module for Temperature/Low‑level mV on Modicon TSX Premium

The Schneider Electric TSXAEG4111 is an analog input module for Modicon TSX Premium systems, typically used to bring thermocouple and other low‑level mV signals into the PLC with stable accuracy. From my experience, it’s a sensible pick when you need reliable temperature measurement across multiple points without complicating your rack layout. You might notice that it slides into a standard TSX Premium rack slot and communicates through the backplane, so wiring stays neat and commissioning is straightforward in most cases.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL
• Each unit is visually inspected and powered on for basic functional checks before dispatch, which typically avoids surprises on site.

Key Features

• Thermocouple/mV inputs – Designed for temperature sensing from common thermocouple types or other low‑level millivolt sources (typical J/K/T/E and similar).
• Multi‑channel measurement – Suits multi‑point thermal monitoring on lines, ovens, or HVAC zones where you need compact density in the TSX rack.
• Backplane integration – No separate communication wiring; the module exchanges data with the TSX Premium CPU over the rack backplane.
• Industrial‑grade stability – In many cases, maintains stable readings in control cabinets with varying ambient conditions when basic ventilation is respected.
• Diagnostics on the front panel – Status indications help pinpoint channel wiring or sensor issues quickly during commissioning.
• Space‑efficient, single‑slot format – Keeps cabinet width tight and leaves room for additional I/O or motion modules.

Technical Specifications

Where it fits best

Typical use cases include multi‑zone oven monitoring, heat‑treatment skids, chilled‑water loops, and packaging line hotspots. One thing I appreciate is the predictable behavior during cold starts; temperature channels come up clean when sensors are wired correctly and shielded to good practice.

A maintenance manager recently shared that swapping a faulty thermocouple was “a 10‑minute job” thanks to the labeled terminals and status LEDs—no need to rework the program, just a quick channel check on the HMI and back to production.

Related or Supporting Products

• TSXAEY414 / TSXAEY800 – Analog input modules typically for voltage/current; choose these if your sensors are 0–10 V or 4–20 mA rather than thermocouples.
• TSXPSY Series – Power supplies for TSX Premium racks; ensure adequate backplane power when adding multiple analog modules.
• TSX RKY Racks – TSX Premium base racks; select slot count based on present modules plus future expansion.
• TSX P57 CPUs – TSX Premium processors; the TSXAEG4111 exchanges process values with these CPUs via the backplane.
• Migration note – If you’re planning a phased upgrade, comparable temperature inputs on Modicon M340/M580 platforms are typically found in the BMX AMI/BMX ART ranges; signal types and channel counts differ, so check the exact I/O map before migration.

Installation & Maintenance

• Cabinet & environment – Install in a TSX Premium rack within a ventilated control cabinet. Keep ambient within the typical 0–60°C range and humidity non‑condensing.
• Wiring practices – Use shielded thermocouple/mV cables, run them away from VFD power lines, and ground shields at a single point. Verify polarity at the terminal block; reversed T/C polarity is a common issue.
• Cold junction & calibration – For thermocouples, confirm CJC method (internal or external) during setup. Periodically validate a channel with a known reference; yearly checks are typically sufficient for most plants.
• Firmware and backup – Keep CPU firmware aligned with the project version and back up the PLC program after adding or re‑addressing channels.
• Cleaning – Light dusting of the module front and ensuring terminal screws stay tight will help avoid intermittent readings.
• Safety – De‑energize the rack before inserting/removing modules. Confirm that sensor wiring is isolated from high‑voltage circuits.
