choice of lens or Fiber Optic Cable. ATTENTION: Installation in hazardous environment locations shall be made according to ANSI/ISA-RP 12.6 and other applicable codes and standards. ATTENTION: These parameters must be adhered to. If not, injury may be caused to person or property. 2 Rockwell Automation Publication 42DR-IN001B-EN-P - May 2016 Intrinsically Safe Sensor ? Adjustable input sensitivity. ? RF interference protected. ? No false turn-on pulse. ? Synchronous detection circuitry avoids ambient interference. ? Switch selection for light or dark operation. ? Dual open collector outputs provide current sink (NPN) and current source (PNP) capabilities. – Load voltage 29.5 V DC maximum – Load current 20 mA maximum ? Response time: 1 ms ? Status indicator alignment: visible 360° ? NEMA 4X corrosion resistant, high impact housing. ? UL Listed. Why Intrinsically Safe Explosion prevention is a prime consideration in plants and facilities containing hazardous atmospheres where “explosion-proof ” housings are used. The main fault with the “explosion-proof ” housing system is that a single human error could create a light explosion probability. Such occurrences as, failing to tightly replace covers on “explosion-proof ” housings, failing to shut off the power before removing the cover of such a housing, and damaging the machined surfaces of such covers are all prime examples. Intrinsically Safe systems are now recognized as a more highly desirable means of providing automated control functions in explosive environments. The technique relies on the inherent parameters of electronic circuits, so that no energy can be released under normal or abnormal operating conditions, of sufficient magnitude to ignite a
