Schneider Electric TSXAEM821 Analog Input Module

The Schneider Electric Telemecanique TSXAEM821 is an 8-channel analog input module for Modicon TSX PLC systems that converts field analog signals into digital data for processing. It supports high-level voltage and current inputs with signals of ±10 V, 0–20 mA, and 4–20 mA (configuration dependent) and is designed for rack-mount installation as an analog I/O expansion module. Widely used in process automation, factory equipment, water treatment, conveyors, and industrial machinery, it enables reliable analog data acquisition for control systems and legacy automation maintenance, with OEM direct replacement capabilities. Manufactured by Telemecanique (Schneider Electric), the TSXAEM821 is compatible with Modicon TSX PLC systems and is a discontinued legacy automation module.
