8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B47 linearized thermocouple input module isolates, filters, amplifies, and linearizes a single channel of temperature input from a thermocouple and provides an analog voltage output.

Linearization is accomplished using a four breakpoint piecewise linear approximation.

The 8B47 linearized thermocouple input module can interface to industry standard thermocouple types J, K, and T and has an output signal of 0 to +5V. Each module is cold-junction compensated to correct for parasitic thermocouples formed by the thermocouple wire and screw terminals on the mounting backpanel. Upscale open thermocouple detect is provided by an internal pull-up resistor.

Signal filtering is accomplished on the 8B47 linearized thermocouple input module with a 3-pole filter optimized for time and frequency response which provides 70dB of normal-mode rejection at 60Hz. One pole of this filter is on the field side of the isolation barrier for anti-aliasing, and the other two are on the system side.

A special input circuit on the 8B47 linearized thermocouple 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.

The 8B47 linearized thermocouple 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 8B47 linearized thermocouple input module.
