Product Overview

The ABB AI893 3BSC690141R1 S800 I/O Systems Analog Input Module is designed for measuring a variety of process signals with high accuracy and precision. This module features 8 differential input channels that can handle 2-wire or 3-wire RTD (Resistance Temperature Detector) sensors and Thermocouples (TC). It provides flexibility and reliability for use in hazardous environments due to the inclusion of intrinsic safety protection components on each channel, eliminating the need for external devices.

The module is well-suited for applications requiring high-precision temperature measurements, such as industrial process monitoring and control, especially where RTD and thermocouple sensors are used.

Key Features

• 8 Input Channels: Supports 2-wire or 3-wire RTD and Thermocouple sensors, allowing versatile measurement options.
• Intrinsic Safety Protection: Ensures safe operation in hazardous environments by preventing electrical hazards.
• Cold Junction Compensation: Channel 8 can be used to measure ambient temperature, serving as a cold junction for channels 1 through 7.
• Configurable Cold Junction Measurement: Users can choose to either use a fixed temperature setting or measure the cold junction temperature with a 3-wire Pt 100 sensor.
• Resolution: 15-bit + sign resolution for precise temperature readings.
• Ex Certified Inputs: The module is Ex certified for hazardous environments, ensuring compliance with safety standards.
• Compact Size: Designed for easy installation in both Ex and non-Ex applications, with compatibility with MTU units like TU890 and TU891 for efficient wiring.
• Dimensions and Weight: 45 x 102 x 119 mm, 0.16 kg, making it compact and easy to integrate into existing systems.
