Analog Data Bits

The first twelve bits represent the analog

data in binary format.

Output Enable

The last output can be used to update

outputs. If this output is OFF, the outputs

will be cleared.

Module Resolution

Since the module has 12-bit resolution, the

analog signal is converted into 4096 counts

ranging from 0–4095 (2

). For example,

send a 0 to get a 4mA signal, and 4095 to

get a 20mA signal. This is equivalent to a

binary value of 0000 0000 0000 to 1111

1111 1111, or 000 to FFF 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.
