DI-8B32 Analog Current Input Modules
Each DI-8B32 module isolates, filters and amplifies a process current input signal and provides an analog voltage
output.
Current to voltage conversion is accomplished internal to the module to ensure high accuracy.
Signal filtering is accomplished with a three-pole filter optimized for time and frequency response which provides
70dB of normal-mode-rejection at 60Hz. One pole of this filter is on the field side of the isolation barrier for anti-
aliasing, and the other two are on the system side.
A special input circuit on the 8B32 module provides protection against accidental connection of power-line voltages
up to 30VAC. Isolation is provided by optical coupling to suppress transmission of common mode spikes or surges.
The module is powered from +5VDC, ±5%.
