The ASI451119 is a DIN rail mounted analog signal isolator transmitter for standard 4-20mA control circuits that provides electrical isolation between the input, output and power circuits. The analog signal isolator can be mounted directly in the control panel or remotely near the field devices due to the high level of isolation. The unit is factory calibrated to allow for quick and easy installation and the galvanic isolation eliminates problems associated with ground loops, transient and unwanted noise interference. The Zero and Span adjustments are provided for precise calibration after installation and for long term service. The ASI analog signal isolator transmitter has been designed to compensate for load variations and the compact 17.5mm wide housing will save space in your control panel. Loop powered, multi-channel and splitters are also available along with user programmable models. Designed with pluggable terminals for easy installation and removal.
