Delivering Accurate Control Signals to Field Actuators
The Schneider Electric 140AVO02000 is a dedicated analog output module for the Modicon Quantum series. This module provides precise command signals to control valves, drives, and other analog devices. It converts digital values from the PLC into stable analog current outputs. Consequently, it serves as a critical interface for closed-loop process control and regulation.
Technical Specifications and Signal Performance
This output module from Schneider offers four independently configurable output channels. Each channel delivers a high-resolution analog signal for accurate device positioning. Furthermore, the module requires four output words for addressing within the processor’s memory map.

Key Features and Control Application
The 140AVO02000 directly interfaces with devices like variable frequency drives (VFDs) and I/P converters. The 12-bit resolution ensures smooth and precise modulation of the output signal. Moreover, the module’s isolated design prevents ground loops and enhances system reliability. Therefore, it is essential for applications in process industries like chemical, pharmaceutical, and water treatment.
Application Context and Signal Utilization
Engineers typically use this module for speed control, pressure regulation, and flow metering. For example, a single channel can command the speed reference of a motor drive. Another channel might position a control valve via an I/P transducer. The 140AVO02000 enables the Quantum PLC to implement advanced control algorithms like PID. Thus, it directly translates digital control decisions into precise physical actions.
Installation and Configuration Process
First, install the module into a compatible 140XBP Quantum baseplate within your control rack. Next, connect the field actuator wires and the required 24V DC loop power to the terminal block. Then, use Unity Pro software to configure each channel’s output range and scaling parameters. Finally, test each output by writing values from the PLC logic to ensure proper actuator response.
