  • Pin Compatible with 1B41 Isolated RTD Conditioner 

The 1B51 is a precision, mV/thermocouple 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 specially suited for harsh environments with extremely high common-mode interference. Unlike costlier solutions that require separate dc/dc converters, each 1B51 generates its own input side power, providing true, low cost channel-to channel isolation.

Applications
  • Multichannel Thermocouple Temperature
  • Measurement
  • Low Level Data Acquisition Systems
  • Industrial Measurement & Control Systems
