B&B Electronics I-7021-P Datasheet
I-7021/ I-7021P - 5003 1/2
Models: I-7021, I-7021P
12-bit/16-bit Analog Output Module
Model I-7021
I-7000 is a family of network data acquisition and control modules providing analog to digital, digital to
analog, digital input/output, timer/counter and other functions. The modules can be remotely controlled by a
set of commands.
The I-7021 is a single-channel analog output module that uses the D/A converter to convert digital data into
analog output signals with 12-bit resolution and current read-back function. The I-7021P is similar to I-7021
but enhanced to 16 bit resolution.
