Schneider Electric TSX 171 2028 Programmable Logic Controller Module

The Schneider Electric Telemecanique TSX 171 2028 Programmable Logic Controller Module is a Modicon TSX 17-10 PLC, version 1.2, with integrated relay outputs designed for industrial machine and process automation. It runs on 110–240 VAC 50/60 Hz, includes 8 KB internal RAM, 12 × 24 VDC isolated digital inputs, and 8 relay outputs (each with 1 N/O contact) supporting 24–240 VAC or 24 VDC on the relay side, and it uses PL7-1 Boolean language for programming with an RS-485 programming port. The unit accommodates up to two discrete I/O extension modules, provides an EEPROM/EPROM cartridge slot for memory expansion, and is intended as an OEM direct replacement for Modicon TSX 17 systems; however, it is a discontinued legacy PLC platform with common replacements including Schneider Electric TSX1712028 and OEM equivalents TSX1712028.
