STAHL safety isolators provide a compact, cost-effective and easy-to-connect way to provide intrinsic safety and galvanic separation between a control system and field devices in a hazardous location. Digital and analog modules are available in single or dual-channel versions; a temperature module is also available. Digital and analog modules are rated for SIL applications and analog modules are HART compatible. The optional pac-BUS system can save cost and wiring time with modular accessories that allow modules to snap onto a DIN rail. These STAHL safety isolators have a 1-year warranty.
