ABB AI01｜Analog Input Module｜
AI01
1. Channels and isolation
Total channel: 16 analog inputs, divided into 2 groups of 8 channels, electrically isolated between groups
Isolation withstand voltage: 1500V AC/1min, suppressing interference from ground loops and frequency converters
Two independent ADCs, each with 8 channels sharing 1 analog-to-digital conversion chip
2. Support signal (single channel software free configuration)
Current: 4-20mA DC (two-wire transmitter, module built-in loop power supply)
Unipolar voltage: 0-5V, 1-5V, 0-10V
Bipolar voltage: -10V~+10V
Current mode input impedance 250 Ω; Voltage mode ≥ 250k Ω
3. Accuracy and Diagnosis
A/D resolution: 12-16 bits (with polarity, software optional)
Full range accuracy: ± 0.1% FS
Temperature drift: ≤± 0.003%/℃
Wire breakage detection: Report an alarm within 15 seconds of a 4-20mA circuit wire breakage
Short circuit protection: automatic current limiting of 96mA for current circuit short circuit, protecting channel circuit
4. Scanning speed
Single 8-channel group refresh: 22.5ms
Full refresh of all 16 channels: 180ms
