Product Details:

Schneider 140ACO02000 is a rack-mounted 4-channel analog output module designed for Modicon Quantum PLC automation systems. This module receives digital control values from the Quantum CPU over the backplane bus and converts digital signals into stable 4-20mA bipolar current signals to regulate field control valves, positioners and other proportional actuators. It adopts 12-bit high resolution conversion, delivering an accuracy of ±0.2% full scale at 25°C, which ensures precise adjustment for closed-loop process control. Each of the four independent channels supports 4-20mA signal output, with a loop voltage requirement of 12V DC to 30V DC to match most standard field instruments. Built-in module self-diagnostic circuits monitor channel status, open circuit and internal hardware faults, feeding fault alarm information back to the PLC CPU for fast on-site inspection and maintenance. Industrial-grade PCB design has strong resistance to mechanical vibration and electromagnetic interference, suitable for continuous operation in power plants, petrochemical plants and water treatment control environments. Installed in standard Quantum rack slots, this analog module communicates reliably with the backplane to receive control commands from the CPU. Widely applied in critical process automation projects, this analog output hardware is a key component of Modicon Quantum control systems. It enables operators to accurately adjust field process parameters such as flow and pressure, stabilizes production conditions and lowers unexpected equipment shutdown risks.
