SCHNEIDER BMXART0414H Analog Input Module

Product Overview
The SCHNEIDER BMXART0414H is a Modicon X80 series analog input module designed for Modicon M340 / M580 PLC systems. It is a 4-channel high-precision low-level input module used for measuring very small signals such as millivolt, thermocouple, RTD, and resistance inputs. It is suitable for severe industrial environments (H version = extended temperature + rugged design).
