Georg Fischer 6400 Data Sheet

Signet 6400 Intrinsic Safety Barriers

Description

George Fischer Signet offers single
channel intrinsic safety barriers for
use with the 515, 525 and 2517 pad­dlewheel flow sensors.

Both versions use a 1/2 inch wide
housing which snaps directly to
a 35mm DIN rail. Once mounted,
an electrical connection is formed
between the barrier and the rail.
The rail serves as the intrinsic safety
ground bus when connected to the

designated grounding point. Two
additional ground lugs are provided
and may be used as a redundant
grounding method or for terminating
shields.

Each barrier also contains a replace­able 160mA fuse cartridge for each
channel. Safety barriers are polarity
sensitive devices and are available in
+DC and AC voltage ratings.

Features

• One step, snap-on
35mm DIN rail mount­ing and grounding

• Replaceable 160mA
fuse

• Lowest internal

resistance

• Common 1/2 in. wide
housing for single and
dual channel

versions

• Short-circuit proof
connections

• FM, UL, CSA approved

• Compatible with

Signet 515, 525 and

2517 flow sensors
