For monitoring and controlling central safety functions in multiple burner systems on
industrial furnaces, checking of the valves and system for tightness using a valve proving
system, safe recording of the furnace chamber temperature on high temperature equipment by a temperature monitor or temperature limiter, long service life due to replaceable load module for fail-safe outputs, can be programmed according to customer
requirements, EU certified, FM and EAC approved, certified for systems up to SIL 3
(compliant with PL e), FCU..H0: CSA approved.
