The 5B35 is a single-channel signal conditioning module from Analog Devices that can amplify, protect, filter, and isolate analog input. The module can isolate and protect a wide variety of four-wire RTDs and generate a linearized, highly accurate output of 0 to +5V. The module circuitry can withstand 240V rms at the input screw-terminals. All 5B35 series modules are mix-and-match and Hot Swappable.
The 5B35 is a single‑channel signal‑conditioning module that amplifies, filters, isolates and protects four‑wire RTDs, providing a linearized 0‑to‑+5 V output. It features 1500 V rms continuous isolation, +0.05 % span accuracy, and a compact 2.27" × 2.32" × 0.595" size.
The handbook includes functional block diagrams, pin‑configuration tables, model variants, mechanical dimensions, environmental limits, and performance specifications such as bandwidth, noise, and common‑mode rejection. It also notes that the modules are hot‑swappable and approved for hazardous locations.
