Description
Product Overview
The HIMA H6200A is a high precision analog signal isolation and conversion module for HIMA safety instrumented systems (SIS). It receives analog process signals from field transmitters such as pressure, temperature and flow instruments, provides galvanic isolation, signal conditioning and conversion, then sends standardized 4-20mA signals to safety logic solver. The module is designed for hazardous industrial environments, used for Emergency Shutdown (ESD), Fire & Gas (F&G) and burner management systems in oil & gas, petrochemical and power plants. It serves as a direct drop-in replacement spare for legacy HIMA safety racks.
