Blue Jay Technology offers the industry's best selection of isolators. Dozens of models are now available to meet your needs. Select from single and dual-channel models with AC, DC, or loop-powered operation. Signal splitters deliver dual outputs from a single source. And whether you need a unit that sinks or sources current, Blue Jay has the right solution for you. Optical or galvanic isolation eliminate ground loop errors, reduce noise, and block high voltage transient surges. Our multi-channel modules reduce costs and save space. Models with push-button calibration simplify installation and maintenance tasks. Units with mini USB port preset for 4-20mA input/output required.
