This document describes the features of the 7B Series signal conditioners, including small size, low cost, and wide output voltage range. The product is an interface module that amplifies and filters a process-current input signal and provides a precise output linearly related to temperature. It is suitable for industrial signal conditioning, isolation, and filtering applications.
The 7B32 is a single‑channel signal‑conditioning module that interfaces, amplifies and filters a process‑current input, delivering a precision output of either +1 V to +5 V or 0 V to +10 V. It offers high isolation (1500 V rms), low non‑linearity (+0.02 %), and accuracy of ±0.1 % while supporting hot‑swap operation in a backplane system.
The handbook details mechanical dimensions, environmental limits, pin‑out assignments, and electrical specifications such as input range, output range, power‑supply requirements, and protection features. It also lists available models, typical performance data, and compliance with industry standards.
