MA-ISOLATING REPEATER SERIES 9164

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
