EHELP: STA Analog Output Protection

EHELP: STA Analog Output Protection
Q:  In specifying the Moore STA / HLPRG / 3PRG / U / -AO [DIN] our end user has a concern about electrical protection for the analog output. The desire is to use 4-20mA Output Loop Voltage sourced by DCS for the AO; however, this voltage may fault at up to 132 VAC. Should our design add fuse protection in the external voltage circuit upstream of the STA to protect it from these surges? Or does the STA include features that protect it from these faults?

Burner Management System Signal Splitter Application for a Pulp and Paper Mill

Burner Management System Signal Splitter Application for a Pulp and Paper Mill

A pulp and paper mill had a black liquor BMS (Burner Management System) that per NFPA 85 requires that its safety logic system be totally independent from other logic systems.  The challenge was they required that key temperature and pressure signals also get monitored and recorded by their BPCS (Basic Process Control System). Learn how Moore Industries solved this problem.

E-HELP: FDY Frequency-to-DC Converter Options for Class I, Div 2 Locations

E-HELP: FDY Frequency-to-DC Converter Options for Class I, Div 2 Locations

Q: I would like to use either FDY/PRG/4-20MA/12-42DC [HPDN] or FDY/PRG/4-20MA/12-42DC [BH2NG] and I want to install it in a control panel enclosure rated Type 4X. I need to ensure it is suitable for Class I, Div 2. Which one is the best solution?

EHELP: HIX Minimum Output Value

EHELP: HIX Minimum Output Value

Q:  HIX Application - It appears that if the "Primary Master" loop (input loop side of the HIX) is broken or open circuited, the "Secondary" loop (output loop side of the HIX) will be 0mA.   Is this true?  Maybe I can put a zener across the primary process terminals to keep the current loop when the process opens? Also, are both or either loops bi-directional HART? I have a 4-20mA input signal that I'd like to share between two 4-20mA/HART process loops. Actually, we currently use another vendor's device to "split" one 4-20mA input to four process loops but it doesn't pass HART.
