Dataforth Corporation 8B41 Voltage Input Modules, 1kHz Bandwidth 8B41-09

Description
8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B40 or 8B41 module isolates, filters, and amplifies a voltage input signal and provides an analog voltage output. Signal filtering is accomplished with a 5-pole filter optimized for time and frequency response which provides 100dB per decade of normal-mode rejection above 1kHz. One pole of this filter is on the field side of the isolation barrier for anti-aliasing, and the other four are on the system side. A special input circuit on the 8B40 and 8B41 modules provides protection against accidental connection of power-line voltages up to 240VAC. Clamp circuits on the I/O and power terminals protect against harmful transients. Isolation is provided by optical coupling to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, ±5%. The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise.

Datasheet Summary
Powered by GS/AI

The 8B41-09 is a voltage input module that isolates, filters, and amplifies a -40V to +40V input signal to provide a -5V to +5V output. It features 1500Vrms isolation, 100dB common-mode rejection at 50Hz or 60Hz, and 1kHz bandwidth with 100dB per decade normal-mode rejection above 1kHz. The module has ±0.05% accuracy, ±0.02% linearity, and output noise of 500μVrms. It is powered by +5VDC ±5%, draws 25mA, and operates over a temperature range of -40°C to +85°C. The package measures 1.11" x 1.65" x 0.40" (28.1mm x 41.9mm x 10.2mm). Input protection is provided against continuous 240VAC connections and transient events per ANSI/IEEE C37.90.1. It is UL/cUL listed, CE compliant, and designed for Class I, Division 2 hazardous locations.
