Description
Short description:WAGO’s passive isolator (2‐channel) electrically isolates and filters 0(4) … 20 mA standard analog signals, while drawing power for signal transmission from the input circuit. The connected sensor supplies the passive isolator with the required power to energize the connected load.Features:No additional supply voltage required3-way electrical isolation with 2.5 kV test voltage
