3B31 - Isolated Voltage Input

Download the 3B31 datasheet PDF. This datasheet also covers the 3B variant, as both devices belong to the same isolated voltage input family and are provided as variant models within a single manufacturer datasheet.

General Description

The 3B30 & 3B31 are narrow-bandwidth (3Hz) single-channel signal conditioning modules which amplify, isolate, filter and protect analog input voltages and provide simultaneous precision voltage and current outputs.

Key Features

  • Interfaces, amplifies, & filtersanalog input voltages. Narrow-bandwidth (3Hz) single-channel single conditioning. Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 220v rms at the input screwterminals Current output withstands 130V rms without damage. All 3B30 & 3B31 series modules are mix-and-match and Hot Swappable Figure 1. 3B30 & 3B31 Functional Block Diagram.
