BMXART0814 8-Channel Analog Input Module ±40mV to ±1.28V | Schneider Electric

The Original New Schneider Electric BMXART0814 is an 8-channel isolated low-level analog input module for the Modicon X80 I/O platform, designed for high-precision measurement of thermocouples, RTDs, and low-level millivolt signals in industrial automation and process control systems. It supports a wide range of input types including thermocouples (B, E, J, K, L, N, R, S, T, U), RTDs (Pt100, Pt1000, Ni100, Ni1000, Cu10), resistors (400Ω, 4000Ω), and low-level voltage signals (±40mV to ±1.28V). Part of the common I/O platform for Modicon M340 and M580 Programmable Automation Controllers (PACs), this module provides channel-to-channel isolation (750V DC) and high-resolution 16-bit Sigma-Delta conversion.
