The 3B34 Rev. 0 is an isolated, linearized RTD input module that amplifies, linearizes, and protects analog input voltages from a wide variety of two-, three-, and four-wire Resistor Temperature Detectors (RTDs). The module provides a constant +10V bridge excitation voltage and simultaneous precision voltage and current outputs linear to input temperature. RTD excitation current and three-wire lead resistance compensation provide a complete signal conditioning solution. The module circuitry can withstand 220V rms at the input screw-terminals. All 3B34 series modules are mix-and-match and Hot Swappable.
