The 5B47 Rev. 0 is an isolated thermocouple input module from Analog Devices that amplifies, protects, filters, and isolates thermocouple inputs. It supports J, K, T, E, R, S, and B-type thermocouples and outputs a precision output of 0 to +5V. The module circuitry can withstand 240Vrms at the input screw-terminals.
The 5B47 is a single‑channel, isolated thermocouple input module that amplifies, filters and linearizes signals from J, K, T, E, R, S and B‑type thermocouples. It provides a protected precision output of 0 to +5 V and can withstand 240 V rms at its input terminals, making it suitable for harsh industrial environments.
The handbook includes functional block diagrams, model tables, pin‑configuration details, mechanical dimensions and environmental ratings. It also lists approved safety standards (FM, CSA) and compliance with EMC directives, helping designers integrate the module into measurement and control systems.
