Product Features
ABB IMASI23 has multi-signal compatibility, supporting 12 types of thermocouples, including J, K, T, E, R, and S, as well as millivolt signals ranging from -100 mV to 100 mV, and RTD sensors such as PT100 and CU50.
ABB IMASI23 features 24-bit resolution to ensure signal conversion accuracy, channel isolation (250V DC/VRMS), and open-circuit detection functionality to enhance interference resistance.
ABB IMASI23 incorporates an automatic calibration mechanism to compensate for component aging and temperature drift, eliminating the need for user intervention.
ABB IMASI23 supports automatic cold-junction temperature compensation for thermocouple inputs, improving temperature measurement accuracy. Modules can be replaced while the system is running, minimizing downtime.
Product Using Principle
ABB IMASI23 uses three edge connectors for signal input and power supply:
P1: Connects to a 5V DC power supply.
P2: Communicates with the controller via the I/O expansion bus.
P3: Receives field signals from the terminal unit, supporting direct connection of three-wire RTDs and thermocouples.
Each channel can be independently configured for input type and range. Signals are converted via a 24-bit A/D converter and processed through linearization algorithms (e.g., RTD nonlinear correction) to output engineering unit values, which are then transmitted to the controller for logical operations and control decisions.
