Dataforth Corporation 8B41 Voltage Input Modules, 1kHz Bandwidth 8B41-12

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 8B41-12 is a voltage input module that isolates, filters, and amplifies analog signals from −60V to +60V and provides a −5V to +5V output. It features a 1kHz bandwidth, ±0.05% accuracy, ±0.02% linearity, and 100dB common-mode rejection at 50/60Hz. Input protection supports continuous 240VAC exposure and complies with ANSI/IEEE C37.90.1 transient standards. The module provides 1500Vrms isolation, operates from a +5VDC ±5% supply drawing 25mA, and is housed in a 1.11" × 1.65" × 0.40" package. It is rated for operation from −40°C to +85°C, meets EN61000-6-4 and EN61000-6-2 emissions and immunity standards, and is certified for Class I, Division 2 hazardous locations. The device is RoHS III compliant and UL/cUL listed.
