The 7B41 Rev. 0 is a signal conditioner that interfaces, amplifies, and filters unipolar and bipolar voltage inputs. The module provides a precision output of either +1V to +5V or 0V to +10V. All 7B41 series modules are mix-and-match and Hot Swappable. It is suitable for industrial signal conditioning, signal isolation, and signal filtering applications.
The 7B41 is a single‑channel signal‑conditioning module that interfaces, amplifies and filters unipolar and bipolar voltage inputs, providing a protected precision output of either +1 V to +5 V or 0 V to +10 V. It offers up to 1500 V rms continuous common‑mode isolation, high accuracy, and hot‑swappable operation for industrial process‑control environments.
The handbook includes functional block diagrams, pin‑out tables, mechanical dimensions, and a full set of electrical specifications such as non‑linearity, bandwidth, and power‑supply requirements, enabling designers to integrate the module into rack‑mount backplanes and custom instrumentation.
