Input Mode (Characteristics) BFM #0
For the 4AD, there are two types of input characteristics: voltage (-10 to +10V) and current (4 to 20mA, -20 to
+20mA) input characteristics. The input characteristics depend on the set input mode as described below. For
each input range, there are 3 input modes.
