Isolated RTD Signal Conditioner

The 1B41 is a precision, isolated, RTD signal conditioner that incorporates a circuit design utilizing transformer based isolation and automated surface mount manufacturing technology. It provides an unbeatable combination of versatility and performance in a compact plastic package. Designed for measurement and control applications, it is especially suited for harsh environments with extremely high common mode interference. Unlike expensive solutions that require separate dc/dc converters, each 1B41 generates its own floating current excitation, providing true low cost channel-to channel isolation.
