The TEC Model 156 Analog Signal Isolator is a qualified analog signal isolation device providing better than 120 dB (at 60 Hz) isolation between input and output. The input and output ranges of available models are tabulated below. Effective isolation is provided while powering the isolator from the non-1E-side.

The TEC Model 156 is designed for field mounting. For multiple isolators and train separation, qualified NEMA enclosures and wall mountings are available. Type testing of the TEC Model 156 is in accordance with IEEE Standards 323-1974, 344-1975, 381-1977 and 472-1974.
