Schneider Electric 140AC002000C Analog Output Module

Schneider Electric 140AC002000C Analog Output Module is a four-channel current-output module designed for Modicon Quantum (TSX Quantum) PLCs. Each of its four isolated outputs delivers a current signal in the 0–20 mA or 4–20 mA range, enabling direct control of valves, actuators, or sensors in process-control loops. The isolation between outputs helps minimize ground-loop noise and interference in harsh industrial environments, while the compact 4-channel form factor fits neatly in standard Quantum I/O chassis. This module is part of Schneider Electric's Modicon Quantum family and is commonly used to drive multiple 4–20 mA loop devices in automation systems. According to Schneider Electric’s lifecycle information for analog output modules in the 140ACO02000C family, these parts were discontinued on March 15, 2022, with end-of-service planned for December 31, 2029, making it a legacy solution best suited for retrofit projects or existing installations rather than new designs. Typical applications include process control loops for temperature, pressure, level, or flow, where four independent current outputs enable simultaneous control of multiple field devices within a single Quantum controller ecosystem.
