ABB AI02｜Analog Input Module｜
AI02
1. Channels and signals
Channel: 16 analog inputs, isolated module group (16 channels per group, isolated withstand voltage 1500V AC/1min)
Single channel software switchable signal:
4-20mA DC (two-wire transmitter, module provides loop power supply)
1-5 V DC voltage signal
HART version: HART 5.4, module integrated with 1 HART modem
A maximum of 4 sub variables can be read in a single channel, and a total of 24 HART sub variables can be read in the entire module
Can upload transmitter temperature, range, fault code, and equipment model to DCS logic
2. Conversion and Accuracy
A/D resolution: 12~16 bits with polarity optional, default 16 bits
Accuracy: ± 0.1% FS (full scale)
Temperature drift: ≤± 0.003%/℃
Full module scan refresh: 100ms (faster than AI01)
Circuit diagnosis: Alarm within 5 seconds of 4-20mA disconnection; Each channel has a current limit of 96mA to prevent short circuit and burnout
3. Electrical and mechanical
Backplane power supply: 24VDC ± 10%, typical 100mA, power consumption ≈ 2.4W
Size: 190 (H) × 27 (W) × 106 (D) mm, net weight 240g
Supporting base: HBS01-FPH (horizontal installation), VBS01-FPH (vertical installation), the base needs to be purchased separately
IP20 protection, supports hot swapping
By structuring the information in this manner, the article provides a clear and organized understanding of input channels, transducer supply, and communication implementations in distributed control systems.
