PR 3186 Series Signal Isolators

3186 Slim Series of 6mm Transmitter/Current Isolators

The 3186 Slim Series Isolators providing a 1:1 conversion of 4-20mA signals. The 3186A provide a 2-wire isolation with excitation and can be used to measure Passive input signals. The 3186B is used for Active input signals. Both are loop-powered devices and will cause a voltage drop of ≤3V. Accuracy better than 0.05% over a range of 3.8-20.5mA. Units are ATEX approved for Zone 2 environments.
