Module 12 Bit Input Resolution
When the module voltage inputs are config-
ured for 12 bit resolution, the analog signal is
converted into 4096 (2
12
) counts ranging from
0–4095. For example, a 0V signal would be 0,
and a full scale 5V or 10V signal would be 4095.
This is equivalent to a binary value of 0000 0000
0000 to 1111 1111 1111, or 000 to FFF hexa-
decimal. The diagram shows how this relates to
the signal range.
Each count can also be expressed in terms of the
signal level by using the equation shown.
Module 14 Bit Input Resolution
When the module voltage inputs are config-
ured for 14 bit resolution, the analog signal is
converted into 16384 (2
14
) counts ranging from
0–16383. For example, a 0V signal would be
0, and a full scale 5V or 10V signal would be
16383. This is equivalent to a binary value of 00
0000 0000 0000 to 11 1111 1111 1111, or 0000
to 3FFF hexadecimal. The diagram shows how
this relates to the signal range.
Each count can also be expressed in terms of the
signal level by using the equation shown.
Module 16 Bit Input Resolution
When the module voltage inputs are config-
ured for 16 bit resolution, the analog signal is
converted into 65536 (2
16
) counts ranging from
0–65535. For example, a 0V signal would be 0,
and a full scale 5V or 10V signal would be 65535.
This is equivalent to a binary value of 0000 0000
0000 0000 to 1111 1111 1111 1111, or 0000 to
FFFF hexadecimal. The diagram shows how this
relates to the signal range.
Each count can also be expressed in terms of the
signal level by using the equation shown.
