Schneider | Analog Input Module 140ATI03000

Schneider Electric Modicon Quantum Thermocouple Input Module 140ATI03000

Core Technical Specifications

• The brand is Schneider Electric, and the specific model is the 140ATI03000.
• This module provides 8 analogue input channels dedicated to thermocouple sensors.
• It supports multiple thermocouple types: J, K, E, T, R, and S for various temperature ranges.
• The temperature measurement range spans from -210°C to +1665°C depending on thermocouple type.
• It offers excellent analogue input resolution of 16 bits for precise temperature data.
• The module provides internal cold junction compensation for accurate measurements in 0-60°C ambient conditions.
• You get reliable absolute accuracy error of ±2°C plus 0.1% of reading for most thermocouple types.
• It features excellent common mode rejection of >120 dB at 50/60 Hz to reduce noise interference.

Performance and Safety Features

• The update time for all channels is 1000 milliseconds for responsive temperature monitoring.
• It provides strong isolation between channels and bus (1780 V AC, 2500 V DC for 60 seconds).
• Isolation between individual channels is rated at 300 V DC / 220 V AC for electrical safety.
• The module includes dual filtering options: a notch filter at 50/60 Hz and a low-pass filter at 20 Hz.
• Comprehensive fault detection identifies broken wire and overtacking scale conditions.
• Detailed local signalling uses 18 LEDs (green/red) for clear channel and system status indication.
• It has a moderate bus current requirement of 280 mA from the Quantum backplane.
