Overview
The 140AVI03000 is a Schneider Modicon Quantum analog input module, order code 140AVI03000, providing 8 differential input channels with 16-bit resolution across voltage and current ranges. It draws 2.2 W from the Quantum backplane and mounts to a chassis in the standard Quantum form factor.
Each of the 8 differential inputs accepts voltage signals of +/-10 V, +/-5 V, 0...10 V, or 0...5 V, and current signals of 0...20 mA or 20 mA, all at 16-bit resolution. The module detects broken-wire faults on 4...20 mA loops and overtracking faults on 1...5 V ranges, signalling via a red LED per channel and a red external-fault LED on the faceplate. Accuracy is rated at -0.03 % with linearity error of +/-0.008 %. A single-pole low-pass filter at 847 Hz (+/-20 %) conditions the input, and the module updates all channels every 10 ms. Input impedance is 20 ohms on current ranges; absolute maximum input is 50 V DC or 25 mA without damage. The module consumes 9 input words of backplane addressing.
Applications
This 8-channel analog input module is used in Modicon Quantum racks for process and machine automation — monitoring pressure transmitters, temperature transducers, flow meters, and level sensors that output standard 4...20 mA or 0...10 V signals. Typical installations include water treatment skids, material handling lines, and packaging machinery where multiple analog signals must be digitised at the rack.
Within the Modicon Quantum platform the 140AVI03000 is a mid-density analog input module — 8 channels in a single-wide chassis slot — suited for applications that need differential inputs and fault detection but do not require the higher channel count of a 16-channel module. It is specified by control system integrators and OEMs who standardise on Quantum racks for medium-to-large automation projects.
