Intrinsically safe isolators meet SIL 2/3 requirements
Mike EdwardsProducts intrinsically safe isolators iSpac Stahl
STAHL has expanded its range of intrinsically safe ISpac isolators portfolio. The isolators are 17.6 mm wide and are available as a single- and dual-channel in typical applications, ranging from analog inputs, analog output, discrete input, solenoid driver, RTD, and TC, as well as some specialized applications like frequency converter, serial communication, and vibration transducers.
The ISpac isolators are globally certified (NEC, CEC, ATEX, IECE, EAC, DNV, PESO, KCS) for installation in Zone 2, and Class I, Div. 2 with I.S. signal to Zone 0, and Class I, II Div 1. ISpac modules from series 91XX and 92XX fulfill the functional safety criteria according to SIL 2 or SIL 3.
All modules can be mounted directly on the DIN rail and, snapped onto a pac-Bus, combine across all models to make them future-proof, the company says.
