Problem: How can I sample HART data from a smart instrument without affecting normal loop operation?
Solution: Use the HIM in “Listen” Mode to passively connect it to a loop. This allows it to be added to a loop with a Primary or Secondary HART Master without assuming the role of a Master because it connects passively without assuming the role of the a Master. In “Listen” Mode, the HIM continuously samples HART data from a smart instrument without affecting normal loop operation.
Model Number Example
HIX / 4-20mA / 4-20mA / 12-42DC [DIN]
