TSX3722101 belongs to Schneider Telemecanique TSX Micro compact PLC family. It is an all-in-one base controller with integrated I/O and 3 expansion slots for adding extra digital/analog modules. Power supply DC24V. It has 18 digital inputs plus 0-10V analog input channels and 3 relay outputs onboard. It supports Uni-Telway RS485 serial communication for connecting HMI, variable frequency drives and remote I/O.

This PLC is programmed by PL7 Micro software. It can handle discrete logic control, analog signal acquisition, recipe management and serial data exchange. Front panel LED indicators display RUN, fault and I/O status for quick on-site troubleshooting. It uses backup battery to retain user program and data memory after power failure. Additional expansion modules can be mounted to increase I/O quantity for medium-size automation systems.

Built-in protection includes watchdog fault detection, memory error diagnosis, overcurrent protection from backplane power supply and reverse voltage protection. Protection grade IP20 for cabinet installation, operating temperature range 0~60℃.

TSX3722101 is discontinued legacy Schneider PLC spare part. Many old automation production machines still adopt TSX Micro systems. When the original base unit fails, replacing it with identical TSX3722101 can reuse existing expansion modules, wiring and original PL7 program without redevelopment. Technicians install the PLC base, check battery status, download PLC project and verify I/O and serial communication, so the whole PLC control system resumes operation and reduces downtime.

Before shipment, every TSX3722101 undergoes comprehensive functional inspection including power-on self-test, backplane bus test, digital/analog I/O test, Uni-Telway communication verification and LED status check. All products come with 12-month warranty. Our automation technical team provides remote support for rack installation, program backup, battery replacement and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, TSX3722101 is reliable spare integrated PLC base unit for legacy Schneider TSX Micro control systems. It restores equipment logic control and analog signal processing functions, extends service life of automation assets and avoids high-cost whole control system renovation.
