‹ Using an Analog Reference Card
AI-14B provides 3 channels of bi-polar inputs with 14-bit A/D conversion accuracy (signed bit). The function
of each channel is determined by the setting of F2-01.
AI-14U provides 2 channels of bi-polar inputs with 14-bit A/D conversion accuracy. Channel 1 is a voltage
input and channel 2 is a current input. The sum of channels 1 and 2 is a frequency input. F2-01 does not need
to be set for the AI-14U option card.

„ Setting Precautions
Always set b1-01 (Frequency Reference Selection) to 1 (control circuit terminal) when using the AI-14B for
three channels of independent inputs. When this is done, H1-01 to H1-10 (parameters for multi-function digi-
tal input terminals S3 to S12) cannot be set to 2 (Option/MxC).

F2-01
AI-14 Input Selec-
tion Sets the function for channel 1 to 3 of the AI-
14B analog input reference option card.
0: 3-channel individual (Channel 1: terminal
A1, Channel 2: terminal A2, Channel 3:
terminal A3)
1: 3-channel addition (Summed values of
channels 1 to 3 is the frequency reference)
When set to 0, select 1 for b1-01. In this case,
the multi-function input “Option/MxC selec-
tion” cannot be used.
