The 9164 series mA isolating repeater allows two 4 to 20 mA signal sources to be coupled. For example, it allows four-wire transmitters to be connected to I/O cards designed to be operated with active two wire inputs.
The use of this device therefore saves costs by eliminating the need for additional I/O cards or can be used as the only solution for I/O cards that only operate with two conductors.
- For installation in Zone 1 or Class I, Div. 1 or Zone 2 hazardous areas (depending on the variant)
- Inputs can be intrinsically safe (Ex i), feature increased safety (Ex e) or be non-Ex
- Space-saving, 12-mm wide design
