Do you know instrument JB's?
Submitted by: MuhammadInstrument JB's depend upon hazards area classification.
JB's also can be IS or NIS
For IS signal IS JB's used for NIS signal NIS JB's used
For analog I/p & o/p signal we can use same JB.
But for Digital I/p & o/p we have to use separate JB's. Because digital outputs are powered signal, by wrong connection there may be chances to damage the card.
For DCS I/p & o/p and PLC I/p & o/p we used separate JB's.
