Schneider 140SAI94000S Modicon Analog Safety Input Module

Description

The Schneider 140SAI94000S Modicon Analog Safety Input Module is a high-performance component designed for the Modicon Quantum series programmable logic controller (PLC) platform, engineered for large-scale industrial automation and process control systems. It features 8 safety analog input channels that collect current signals ranging from 4 mA to 20 mA, with a 16-bit resolution and ±0.1% full-scale accuracy to ensure precise, reliable signal capture from field sensors measuring temperature, pressure, flow, and other process variables.

This module integrates seamlessly with Modicon Quantum series PLCs via the backplane bus for high-speed data transmission, eliminating the need for additional communication modules. It meets SIL 2/3 safety standards and includes built-in safety isolation, continuous monitoring, and fault diagnosis functions to support safe system operation and rapid response to safety events. Powered by 24 VDC with a 10 W power consumption, it has an IP20 protection rating, operating temperature range of 0 degrees Celsius to 60 degrees Celsius, and storage temperature range of -40 degrees Celsius to 85 degrees Celsius. It withstands vibration of 3.5 mm displacement at 0.5 to 8.4 Hz and 1 gn constant acceleration at 8.4 to 150 Hz, and is rated for operation up to 2000 meters with a maximum altitude of 3000 meters, and 93% relative humidity, making it suitable for harsh industrial environments.
