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. Applications * Multichannel RTD Temperature Measurement * Industrial Measurement and Control Systems * Data Acquisition System * Complete RTD Signal Conditioning Solution * Resistor Programmable Linearization * Lead Resistance Compensation * High CMV Isolation: 1500 V rms Continuous * Small package: 1.0"x2.1"x0.35" DIP * Low pass filter (fc=3Hz)
