Accepting a broad range of input signals, the DRF series configurable, DIN-rail mount signal conditioners provide up to 3.5 kV of effective isolation between input, output, and power. They accommodate input signals such as ac/dc voltage and current, frequency, temperature (thermocouple and RTD), and process transducers. Each model in the series is available with standard process outputs of either 4 mA to 20 mA or 0 to 10 Vdc (only one output may be used at a time). The conditioners mount on standard 35-mm DIN rails and are particularly suitable for use in chemical, water, and petroleum applications. Price starts at $170. OMEGA ENGINEERING INC., Stamford, CT.
