TSX3721001
Schneider Electric
Overview
The TSX3721001 is a Modular base controller in the Modicon TSX Micro automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon Premium / TSX ecosystem.
Application & Technical Notes
As a modular base controller, the TSX3721001 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Premium / TSX equipment is installed. It hosts the application program, executes the control cycle and orchestrates I/O scanning, communication and diagnostics for the station.
Key published characteristics include an operating temperature range of 32…140 °F (0…60 °C). These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (32…140 °F (0…60 °C)); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -13…158 °F (-25…70 °C). Avoid condensation — the rated humidity is 10…95 % without condensation for operation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Back up the application program and parameter set before any firmware or hardware change; verify the memory/real-time-clock battery where fitted and replace on schedule. Monitor the module health LED and controller diagnostics; plan spares for critical stations to minimise downtime. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the TSX3721001, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm the CPU matches your Modicon Premium / TSX architecture, memory size, firmware revision and any required option/communication modules. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications
The Schneider Electric TSX3721001 is a controller module from the TSX Micro PLCs series equipped with a real-time clock. It features substantial memory capacities, including internal RAM for data and program storage and flash memory. This module supports complex applications and various communication protocols, ensuring flexibility in system design.
Description
| Note | The TSX3721001 model from Schneider Electric's TSX Micro PLCs series operates as a controller module with a dedicated real-time clock. Its memory architecture is robust, consisting of internal RAM capable of 20 Kwords for data management, along with capacity expansions available when utilizing a PCMCIA card, allowing for 128 Kwords of program and data storage. There is also an additional 15 Kwords in flash memory for storing information. Object areas are designed to accommodate up to 256 %Mi, with 1 %MWi allocated for internal data storage and 128 %KWi reserved for constant values. Execution times for processing instructions are efficient, offering 5.88 milliseconds for 100% Boolean operations without a PCMCIA card while supporting a reduced 0.266 milliseconds when using one, depending on the task's complexity. The application structure consists of one fast task, one master task, and up to 16 event tasks, allowing versatile programming capabilities. The master task executes with a system overhead of 1.6 milliseconds, ensuring rapid response and reliability during operation. The device has an IP30 rating and complies with multiple electromagnetic compatibility standards to protect against interference and electrical noise. Operating under a primary voltage range of 100 to 240 V AC, the controller draws an input current of only 2 mA while sustaining a maximum output current of 0.5 A. It is designed to withstand microbreaks of less than 20 milliseconds, improving its resilience. The unit features three integration slots, supporting a serial link with Uni-Telway at 19.2 kbit/s and Modbus RTU at the same rate, facilitating effective communication in automation systems while enhancing connectivity options. |
