Schneider 140ARI03010 Analog Input Module

Description

The Schneider 140ARI03010 Analog Input Module is part of the Modicon Quantum Series, designed to convert analog signals such as temperature, pressure, and current into digital signals for processing by PLC and other controllers. It is ideal for process control applications in industries including petrochemical, power, and metallurgy, where it monitors and controls critical process variables. This module features 8 differential input channels, supporting a range of temperature probes including Pt100, Pt200, Pt500, Pt1000, Ni100, Ni200, Ni500, and Ni1000, with a 13-bit current resolution. Key performance specifications include an input impedance of >=10 MOhm, absolute accuracy error of 0.1 degrees Celsius, linearity error of +/-0.01% of full range +/-0.5 degrees Celsius, and temperature offset accuracy of +/-0.5 degrees Celsius at 25 degrees Celsius, +/-0.9 degrees Celsius between 0 and 60 degrees Celsius. It operates within a temperature range of 0 to 60 degrees Celsius and holds UL, CSA, FM, and cUL certifications. The module offers robust electrical isolation: each channel withstands 1780V AC 47-63Hz for 60 seconds or 2500V DC for 60 seconds against the bus, with 300Vrms AC isolation between channels. Its memory structure includes internal RAM powered by a nickel-cadmium battery, plus support for 1 or 2 PCMCIA memory expansion cards (on specific processors) protected by lithium batteries.
