Product Features
ABB IMASI03 supports ±0.1% reading accuracy and 16-bit resolution, enabling precise capture of minute signal changes, making it ideal for precision control applications.
ABB IMASI03 features a built-in programmable gain amplifier that automatically adjusts the amplification factor based on the input signal range to optimise the signal-to-noise ratio.
ABB IMASI03 supports various signal types, including -10V to +10V voltage, 0 to 20mA/4 to 20mA current, and RTD temperature sensors (e.g., Pt100, Cu50).
ABB IMASI03 includes open-circuit detection and low-drift channel voltage reference to ensure signal stability.
ABB IMASI03 offers 1500V DC electrical isolation, isolating field signals from the control system and effectively resisting electromagnetic interference and surge impacts.
Each channel is equipped with an LED status indicator, providing real-time display of signal validity and module operational status. ABB IMASI03 supports hot-swapping, allowing maintenance without system downtime, thereby reducing system downtime.
Product Using Principle
ABB IMASI03 enables signal interaction through three card edge connectors (P1, P2, P3):
P1 interface: Connects to a 24V DC power supply and analog signals from field sensors.
P2 interface: Connects to the Infi 90 expansion bus for bidirectional data communication with the main controller, transmitting digital signals converted by the ADC and diagnostic information.
P3 interface: Used for cascaded communication between expansion modules.
The workflow is as follows:
Field analog signals are input via the P1 interface and adjusted in amplitude by a programmable gain amplifier.
A 16-bit ADC converter converts the analog signals into digital values with a precision of ±0.1% of the reading.
Digital signals are transmitted via the P2 interface to the MFP module, where the control system performs logical operations and closed-loop control.
The module continuously monitors channel status and provides feedback to the host computer via LED indicator lights and diagnostic protocols.
