As a classified SIL3 device, the new transmitter power supply meets all safety requirements and is approved for intrinsically safe applications according to IEC 61508. The advantage of this is that only a single transmitter power supply is required to build an intrinsically safe signal circuit for SIL3. Until now, two SIL2 devices were needed. These additional costs can now be eliminated. For SIL2 applications there is a considerable benefit. Due to the new transmitter power supply with SIL3 classification, the prescribed test intervals in SIL2 applications are extended. Consequently, work-intensive maintenance is reduced.
