The 8B41-13 is a voltage input module that isolates, filters, and amplifies a ±60V input to produce a 0V to +5V output. It features a 1kHz bandwidth, 100dB per decade normal-mode rejection above 1kHz, and 1500Vrms isolation. Input protection supports continuous 240VAC connections and ANSI/IEEE C37.90.1 transient immunity. Accuracy is ±0.05% of span with ±0.02% linearity, and temperature drift is ±10ppm/°C for offset and ±75ppm/°C for gain. The module operates from a +5VDC ±5% supply, draws 25mA, and meets UL/cUL and CE standards. It is housed in a 1.11" x 1.65" x 0.40" package and rated for operation from -40°C to +85°C.
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.
