IMASI23 | Symphony Analog Slave Input Module ABB Bailey

Manufacturer: ABB

Product No.: IMASI23

The ABB Bailey IMASI23 Analog Input Module is an integral component of the Symphony Enterprise Management and Control System, specifically designed for Harmony rack I/O modules. Here's a breakdown of its features and specifications:

Features:

• Consists of 16 analog input channels capable of handling various types of signals including isolated thermocouple, millivolt, RTD, and high-level analog signals.
• Each channel has its own analog-to-digital converter and can be independently configured for different input types.
• Channels support thermocouples (multiple types), 3-wire RTDs, millivolt inputs, high-level voltage inputs, and current inputs.
• Offers a resolution of 24 bits for analog-to-digital conversion.
• Allows independent selection of input type and resolution for each channel.
• Provides channel isolation and open input detection for enhanced reliability.
• Automatically calibrates during operation to compensate for component aging and temperature drift, eliminating the need for user calibration.
• Offers engineering units conversion for thermocouple and RTD inputs, correcting for nonlinearities using standard linearization tables.
• Supports cold junction compensation for thermocouple inputs.
• Can be removed or installed without shutting down the power to the system.
