EHELP: What is the 2 in IPT2

EHELP: What is the 2 in IPT2

Q:  A field tech told me he installed an IPT2/4-20MA/3-15PSIG/20PSIG/-FA1 [DIN] unit.  In the product bulletin I don't see a purpose for the trailing "2" in the model name, and I don't see an explanation for -FA1.

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.
