The DRI-U is a DIN rail mount signal conditioner for thermocouple, RTD, resistance or voltage inputs, with 1800V isolation between input, output and power. The user configurable input and output offers flexible, wide ranging capability for most temperature signal conditioning applications. The DRI-U is configured via DIP switch for Types J, K, T, E, R, S, B, N, or C thermocouples or Pt, Ni or Cu RTDs. Additionally, functions such as signal linearisation, up or down-scale burnout, number of RTD leads (2, 3 or 4) and voltage or current output are also set via dip-switches.

Accuracy and performance during warm-up and during changes in ambient temperature are maximized. The cold-junction compensation technique utilizes two temperature sensors to measure the differential temperature near the terminal block. Using heat transfer calculations with the measured differential temperature and the known thermal conductivity of the PCB, the terminal junction temperature is determined with extreme accuracy. Even during unstable thermal states such as start-up, ambient temperature changes or changing load or power, the DRI-U Series performs extremely accurate thermocouple temperature measurement.
