The 7B34 series is a family of Analog Devices isolated circuit boards designed for industrial applications. It integrates amplification, protection, filtering functions, and can receive input voltages from a wide range of two- and three-wire platinum, copper, and nickel RTDs, and provide a precision output of either +1 V to +5 V or 0 V to +10 V, linear with temperature.
The 7B34 is a single‑channel signal‑conditioning module that amplifies, filters, and isolates input voltages from two‑ and three‑wire platinum, copper, and nickel RTDs. It delivers a precision output of either +1 V to +5 V or 0 V to +10 V, linear with temperature, and supports hot‑swappable operation in a 19‑inch rack system.
The module offers up to 1500 V rms continuous common‑mode isolation, 120 V rms input protection, and a wide supply range of +14 V to +35 V DC. Detailed specifications include nonlinearity, accuracy, bandwidth, and mechanical dimensions, making it suitable for industrial process‑control and factory‑floor applications.
