ABB IMASI03 Bailey Analog Input Slave Module

   The ABB IMASI03 Bailey Analog Input Slave Module is a high-performance component designed for the INFI 90 process control system. Occupying a single slot in the Module Mounting Unit (MMU), this board conditions up to 16 analog input signals, offering programmable 16- to 24-bit resolution with independent channel configuration.

   The module filters, amplifies, and isolates incoming signals while providing advanced features such as channel isolation, open input detection, and automatic error compensation. Factory-calibrated with self-recalibration capabilities, it compensates for temperature drift and component aging without requiring user intervention.

   Hardware integration is streamlined through three card edge connectors: P1 for supply voltages, P2 for slave expander bus communication with the MFP, and P3 for field wiring via termination units. System addressing is configured through an onboard dipswitch, while jumpers define analog input signal types. This combination of flexibility, precision, and ease of installation makes the IMASI03 ideal for demanding industrial automation applications requiring reliable analog signal acquisition.

   The design of the IMASI03 module, as with all INFI 90 modules, allows for flexibility in creating a process management system. 

1. The IMASI03 conditions (filters, amplifies and isolates) up to 16 analog input signals.

2. The IMASI03 converts analog signals to digital values, adds compensation and corrections as needed, and provides digital values to the MFP through the slave expander bus.

3. Resolution of the analog-to-digital conversion process is programmable over a range from 16 to 24 bits.

4. Input type and channel resolution may be selected independently for each channel, permitting any mix of inputs on a single IMASI03 module.

5. Channel isolation and open input detection are provided for each channel.

6. Input circuit offset, gain and nonlinearity errors are recorded during a one time factory calibration procedure. These measurements provide error compensation during normal operation. The slave does automatic recalibration during normal operation to compensate for component aging and temperature drift. No user calibration is ever required.

   The IMASI03 is widely used in continuous process industries such as chemical processing, oil and gas, and power generation. In these environments, accurate measurement of temperature, pressure, flow, and other analog variables is critical. The module's support for multiple thermocouple types, RTDs, and current signals allows it to interface directly with a wide variety of field instruments.

   Its ability to collect high-quality analog data enables control systems to respond quickly and accurately to changing process conditions, improving safety and operational efficiency.
