Description

The ABB Bailey Infi 90 IMASO11 is an Analog Output Slave Module designed for use within the Symphony Plus and Infi 90 distributed control systems. This module is primarily utilized in high-precision applications, including turbine control, where reliable conversion of digital control signals into analog outputs is required for field device actuation.

Features

• Provides 14 analog output channels.
• Supports both 1 to 5 VDC and 4-20 mA output signals.
• Features 10-bit D/A resolution for precise signal conversion.
• Integrated short-circuit protection with a 50 mA nominal current limit.
• Designed for rack-mounted installation within the Infi 90 or Symphony Plus control environment.

Technical Specifications

Installation Guidelines

• Ensure the control system is powered down before inserting or removing the IMASO11 module from the rack.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.
• Verify that the rack slot is clean and free of debris to ensure proper seating and electrical contact.
• Route analog signal cabling separately from high-voltage or high-EMI power lines to minimize signal interference.
• Ensure proper grounding of the module chassis to the rack backplane to maintain signal integrity and safety compliance.
