The 8B41-05 Voltage Input Module from Dataforth Corporation is designed for monitoring real-world process signals and providing high-level voltage outputs to data acquisition systems. It features a 1kHz bandwidth and utilizes a 5-pole filter that offers 100dB per decade of normal-mode rejection above 1kHz, ensuring effective signal filtering. The module can accept input ranges from ¬±1V to ¬±60V and outputs a corresponding range of ¬±5V. Protection features include input protection against continuous power-line voltages up to 240VAC and transient protection compliant with ANSI/IEEE C37.90.1 standards. The module provides 1500Vrms isolation to suppress common-mode spikes and is suitable for installation in Class I, Division 2 hazardous locations. It operates within a temperature range of -40¬8C to +85¬8C and has a low drift with ambient temperature, making it suitable for high-vibration industrial environments. The 8B41-05 is RoHS III compliant and offers a compact design with dimensions of 1.11,Äù x 1.65,Äù x 0.40,Äù.
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.
