AI Setting

• Channel Mode

The input channels can be set individually to±10 V, 0 to 10 V, 0 to 20 mA, 4 to 20 mA, and 4 to 20 mA

(Burnout).

• Burn-out Value

Burn Out mode indicates when the Current AI has burned out. For example, the 4–20 mA Burn-out

mode is defined in the following diagram:

Users can define Burn-out (BO) values (default = 2 mA) for selected ranges. When input values are in

the Burn Out range, raw data will register as 0000h to indicate that the analog input has burned out.

The definition of raw data is as follows:

Burnout Value (BO) 0.0 < BO < 4.0 User defined (default 2 mA)

Burnout State 0 ≤ AI < BO mA Modbus output 0000h

Under Range BO ≤ AI < 4 mA Modbus output raw data

Normal Range 4 ≤AI ≤ 20.00 mA Modbus output raw data until FFFEh

Over Range XX > 20.00 mA Modbus output FFFFh
