B&B Electronics I-7018 Datasheet
8-channel Isolated Analog Input Module
Model I-7018
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-7018 is an 8-channel analog input module. The I-7018P supports more thermocouple types and
enhances the measurement range of some types.
