AI845 3BSE023675R1 ABB High-density HART analog input module AC 800M System 800xA
ABB AI845 is a new generation 16-channel analog input module in the AC 800M distributed control system, specifically designed for smart factories and digital transformation projects. Based on the high-density advantage of AI815, this module further optimizes the HART communication performance and diagnostic capabilities, supporting full-channel synchronous HART polling. It can efficiently collect the main variable (PV), equipment status, diagnostic information and multivariable data from intelligent transmitters such as pressure, temperature and flow.
Core features
16-channel high-density design
Supports 4-20mA current signal (active/passive compatible)
Input impedance: < 250 Ω (Ensure no impact on circuit power supply)
A single module saves 50% cabinet space compared to traditional 8-channel modules
Full-channel HART 7 compatibility
Each channel independently supports the HART 5/6/7 protocol
Support multi-variable transmission (such as PV, SV, TV, QV)
Configurable HART polling cycle (up to 2 seconds per device)
Seamless integration with System 800xA Asset Optimizer
Spring terminal tool-free wiring
Push-in technology, supporting 0.14-2.5mm ² (26-12 AWG) wires
