ABB IMASI23 Analog Input Module

Product Description

The ABB IMASI23 is a 16-channel universal analog input slave module from the Symphony Plus series (legacy Bailey Infi 90 system). It converts analog signals from field sensors (e.g., temperature, pressure transmitters) into digital data for PLC/DCS control systems. Designed for harsh industrial environments (-25°C to +70°C) with IP20 protection, it ensures reliable operation in process automation applications.

Technical Parameters

Advantages & Features

1. Multi-Signal Compatibility

   • Supports voltage/current/temperature signals with 16-bit resolution and ±0.1% accuracy.

2. Hot-Swap Design

   • DIN-rail mounting enables online replacement without system shutdown.

3. Noise Immunity

   • Channel isolation (1500 VDC) and EMI protection for high-noise environments.

4. Self-Diagnostics

   • Per-channel LED status indicators for open-circuit/overcurrent detection.

5. Seamless Integration

   • Compatible with ABB Symphony Plus systems via backplane or fieldbus (e.g., Profibus)

Application Fields

1. Process Industries

   • Reactor temperature monitoring in chemical plants, pressure sensing in pharmaceuticals.

2. Energy Management

   • Grid voltage/current acquisition, wind turbine condition monitoring.

3. Manufacturing Automation

   • Production line sensor signal processing (e.g., robotic arm feedback).

4. Environmental Utilities

   • Flowmeter data collection in wastewater treatment, HVAC control in buildings.

5. Transportation

   • Sensor signal conversion for port cranes, railway signaling systems.

Precautions

1. Installation

   • Avoid conductive dust; ensure ambient temperature ≤50°C and adequate ventilation.

2. Electrical Safety

   • Disconnect power before wiring; adjust grounding for floating grids (IT systems.

3. Signal Integrity

   • Use shielded cables; maintain ≥50 cm distance from high-frequency devices (e.g., VFDs).

4. Maintenance

   • Clean quarterly with dry air (<3 bar); inspect terminals annually for oxidation.

5. Configuration

   • Verify firmware compatibility with host controllers (e.g., ABB AC450); lock parameters post-commissioning.
