Isolated Barriers With galvanic optical or transformer isolation, these modules provide an interface within the intrinsic safety circuit that is electrically separated from the control system. A key advantage of isolated barriers is that they do not require a ground between the module and the intrinsically safe device. Available in 12.5 mm (0.5 in) and 20mm (0.8 in) widths. Switch Amplifiers Switch Amplifiers are used to transfer digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. Select modules are available with relay output or transistor output, in...
