Intrinsically Safe Modules with Diagnostics

May 5, 2011
Three new fail-safe modules for the Simatic ET 200iSP intrinsically safe distributed I/O system reportedly meet the high safety requirements of relevant standards such as IEC 61508, SIL 3, ISO 13849-1 and PLe.

The modules—8F-DI Ex Namur, 4F-DO Ex 40mA/17.4V and 4F-AI Ex HART—are suitable for applications including emergency shutdown, boiler protection, and protection of fire and gas equipment. For fire and gas applications, the modules have the important diagnostics functions such as “last valid value” and “energize-to-trip.”
