AI Input Range
There are four modes in the analog input range: [0-10 V], [4-20 mA], [0-20 mA], [4-20 mA (burnout)], only
[0-10 V] and [4-20 mA] supports peer to peer networking.
Burnout mode can indicate if the current analog input has burnt out.
The 4-20 mA burnout mode is defined in the diagram at the top of the following page:
Users can define burnout values (BO, default 2mA) for selected ranges. When input values are in the burnout
range, raw data will register as 0000h to indicate analog input burnout. The definition of raw data is as
follows:
Burnout Value (BO): 0.0 < BO < 4.0, user defined (default 2mA)
Burnout State: 0
≦
AI
<
BO mA, S/W output 0000h
Under range: BO

AI
<
4 mA, S/W output raw data
Normal range: 4
≦

≦
20.00 mA, S/W output raw data until FFFEh.
Over range: > 20.00 mA, S/W output FFFFh
The Auto scaling function maps the original AI value linearly to a scaled value. Note that the scaled value’s
Modbus address differs from the original value.
