The Elsag Bailey IMAMM03 is a microprocessor-based INFI 90 Analog Master Module. It accepts and processes as many as 64 analog inputs through compatible analog slave modules.
- Analog Master Module
- Up to 64 analog inputs through slave modules
- 16-bit A/D; 15-bit guaranteed linearity
- 16 high-level inputs: 4-20 mA and documented voltage ranges
The master coordinates slave-module scanning and performs engineering-unit conversion, polynomial adjustment, square-root conversion, thermocouple linearization, alarm/exception handling and trending functions. The slave module selected for each group defines the physical signal type.
Important Notice: Keep the complete IMAMM03 marking unchanged and verify the physical nameplate, revision, companion hardware, and current ABB/Elsag Bailey documentation before installation or replacement.
Apter Power IMAMM03 Manuals and Guides
Important Notice: These are two separate Apter Power documents prepared from the official ABB/Elsag Bailey source named in each document. Confirm the physical nameplate, current manufacturer documentation, and applicable installation or system drawing before installation or replacement.
Control System Integration
Process temperature, pressure, flow and other analog-measurement systems in INFI 90 distributed-control cabinets.
Signal and Data Handling
High-level analog, thermocouple, millivolt or RTD inputs through IMASM01, IMASM02, IMASM03 or IMASM04 slave modules.
Companion Hardware
IMASM01/02/03/04 Analog Slave Modules, module bus, slave expander bus, module mounting unit and the applicable termination unit/module.
Commissioning and Verification
Use IMAMM03 only after confirming its complete nameplate, revision, configuration, connections, and affected system functions.
Read and follow the official manufacturer source and applicable installation instructions before use. Verify the exact complete ordering code from the physical nameplate.
1
Match the slave-module type, range, cold-junction compensation and field wiring to the configured input definition.
2
Do not wire a signal directly from an IMAMM03 description; use the specific slave and termination documentation.
3
Back up configuration and validate each channel after master or slave replacement.
4
Observe the applicable wiring, grounding, approval, environmental, and enclosure requirements.
5
Record the complete model, revision, configuration, and commissioning results before returning the system to service.
