TSX3705001 is Schneider Modicon TSX Micro series compact base PLC controller with integrated digital I/O and two expansion slots, powered by DC24V. It is designed for small and medium discrete automation applications such as packaging machines, conveyor lines, textile machinery and water treatment skids. It supports IEC 61131-3 programming standards and is programmed via PL7 Micro software. It is an end-of-life spare part widely deployed on legacy production equipment.

This controller adopts DIN rail mounting design with IP20 protection class for cabinet installation. It integrates 16 digital inputs and 12 relay outputs locally, while two expansion slots accept TSX series digital I/O, analog and communication modules to expand system I/O capacity up to 144 points. It features 64KB program memory and supports PCMCIA memory card for program backup and memory expansion. Boolean instruction execution speed reaches 0.25µs, handling one master task, one fast task and up to 8 event tasks for high-speed logic response.

It provides RS232 and RS485 serial communication interfaces, supporting Uni-Telway and Modbus RTU protocols to connect operator panels, variable frequency drives and remote I/O modules. Multiple LED indicators on front panel display RUN, STOP, fault, battery and communication status, helping maintenance staff quickly locate faults during on-site troubleshooting. Built-in overcurrent, short-circuit and overvoltage protection circuits protect the controller and peripheral devices against electrical surges. The operating temperature range is 0~60℃, suitable for general factory cabinet environments.

TSX3705001 is obsolete Schneider PLC spare part. Many legacy automated machines still rely on TSX Micro control platforms. When the original base controller fails, replacement with identical TSX3705001 can reuse DIN rail mounting structure, expansion modules and existing PL7 project files. Technicians install the unit, download PLC logic program and verify I/O signals and serial communication, so the machine control system resumes operation and reduces production downtime.

Before shipment, every TSX3705001 undergoes comprehensive functional inspection including power-on self-test, memory test, I/O channel verification, serial communication handshake and insulation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, program download and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, TSX3705001 is reliable spare base controller for legacy Schneider TSX Micro PLC systems. It restores logic control and serial data exchange functions, extends service life of automation assets and avoids whole machine control system renovation.
