Schneider Electric 140DAO84210 Analog Output Module

The Schneider Electric 140DAO84210 Analog Output Module is an 8-channel Modicon Quantum PLC I/O module that converts digital signals into precise voltage outputs to control field devices such as valves, actuators, and drives. Built for rack-mounted integration on the Quantum backplane, it provides channel-to-channel isolation and high-resolution, high-precision voltage outputs (0–10 V) for stable analog control in process automation. As a Modicon Quantum series analog output module, it is compatible with Modicon Quantum PLC systems and commonly used in process control, chemical plants, manufacturing lines, and energy systems requiring accurate analog signal output. Common replacements include Schneider 140DAO84000, 140DAO85300, and ABB AO810.
