Overview
The 140ARI03010 is a Schneider Modicon Quantum analog input module, order code 140-ARI-030-10, providing 8 channels of RTD input with 13-bit resolution for Pt100/200/500/1000 sensors. It carries CE marking and UL 508 / CSA C22.2 No 142 certification, draws 1.0 W from the backplane, and mounts on a chassis in the Quantum rack.
The module accepts differential RTD inputs and reports temperature with a linearity error of ±0.01 % full scale ±0.5 °C and an accuracy of 0.1 °C. Update time depends on wiring configuration: 1200 ms for 3-wire RTDs, 640 ms for 2-wire or 4-wire connections. Input impedance is 10 Ω, and the module requires 9 input words of addressing in the Quantum backplane. Local signalling includes one green LED for bus communication active, one red LED for external fault, and eight green/red LEDs per channel for on/off and fault status.
Applications
This module sits in a Modicon Quantum automation platform rack, reading temperature from RTD probes in process control, HVAC, and industrial monitoring applications where multiple Pt100 or Pt1000 sensors need to be scanned. Typical installations include chemical processing skids, food-and-beverage temperature zones, and environmental chambers where the 8-channel density reduces rack slot count versus lower-density alternatives.
Compliance & certifications
The module carries CE marking, UL 508 and CSA C22.2 No 142 certification, FM Class 1 Division 2 approval, and cUL listing. It is also listed under California Proposition 65. Warranty is 18 months from the date of manufacture.
