TECO SG2-12HT-D - Analog Module; Analog Input Module 4 AI

Chapter 9 Expansion Module 223
Analog Module
The maximal connectible number of Analog expansion module to SG2 is 2*2AO, 1*4PT and 1*4AI.
Analog Input Module 4AI
The 4 channel 12bits analog input module, 4AI, has the corresponding registers, A05~A08, DREC~DREF,
DRE4~DRE7. It can accept either 0~10V or 0~20mA signal, the range of the measured value is different which
depends on the input signal mode. See the below table for more information.
