8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B38 strain gauge input module isolates, filters, and amplifies a full-bridge strain gage input signal and provides an analog voltage output.

The 8B38 strain gauge input module can interface to transducers with a nominal resistance of 100Ω to 2kΩ. Bridge excitation is provided from the module with a stable 10.00V or 3.33V source. Full scale sensitivities of 2mV/V and 3mV/V are offered as standard.

Signal filtering is accomplished on the 8B38 strain gauge input module with a 5-pole filter optimized for time and frequency response which provides 100dB per decade of normal-mode rejection above the filter cut-off frequency. 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 8B38 strain gauge input module provides protection against accidental connection of power-line voltages up to 240V AC. Clamp circuits on the I/O and power terminals protect against harmful transients.

Isolation is provided by transformer coupling to suppress transmission of common mode spikes or surges. The 8B38 strain gauge input module is powered from +5V DC, ±5%.

The 8B38 strain gauge input module is designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise.

A wide range of backpanels, DIN rail mounting options, cables, racks, power supplies and other accessory items are available for the 8B38 strain gauge input module.
