. This barrier adopts knock-down connector with screw terminals. The
intrinsically safe(IS for short) terminals (blue plugs) should be connected
to hazardous area devices and the non-IS ones (green plugs)to the safe
area devices.
Choose for the harzardous area the blue-marked wires. Its minimum
2
cross section area should be 0.5 mm ,and minimum dielectric strength
should be 500V.
The wirings in safe area and hazardous area must be separated,
and both have protection bushes.
A length of 8mm bared wire is locked by the M3 bolt. See as shown
below.
Installation
The isolated barrier should be located at safe area, according to
the related requirements in IEC60079-17(EN60079-17)and
IEC60079-19(EN60079-19).
GS8500-EX series isolated barrier are designed for mounting on
35mm DIN guide rail.
Installation according to the following steps:
(1). First make the bus-powered outlet locked into the guide rail;(If no
bus-powered function,omit this step);
(2). Make the upside of the barrier locked into the guide rail;
(3). Push the downside of the barrier in the rail.
Disassembly
(1).Insert a screwdriver (its edge length≤6mm)into the downside metal
lock of the barrier;
(2).Push the screwdriver upwards,then prize the metal lock downwards;
(3).Take the barrier out of the guide rail.
(1).Before using, please check again whether the module’s Ex-proof
rating accords to the operation conditions, and also wiring and polarity
are correct.
(2).It is disallowable to test insulativity among the terminals with a
megameter. If necessary, the wires must be cut off before testing ,or the
internal fuse would blow.
(3).Every product has been test strictly before leaving factory. If users
find any abnormality in the module, please contact the nearest agent or
our company.
(4).In 5 yeras from the delivery date, if the product works improperly
during normal operation, we will repair or replace it without payment.

Specification
Intrinsic safety description
2-wire HART transmitter, 3-wire transmitter, current source input
isolated barrier(1 input, 2 outputs), provide isolated dc supplies for
transmitters which located in hazardous area. Transfer 4~20mA signal(or
current source signal) which generated by the transmitter form hazardous
area to safe area separately, also allows bi–directional transmission of
HART communication signals . The product needs an independent power
supply.Input circuit,output circuit and power supply are each galvanically
isolated.
(1). The air should not contain any medium corrupting the coat of
chrome,nickel and silver.Moreover,violent quiver and impact or any cause
of electromagnetic induction (such as big current or spark,etc.)must be
avoided when using.
(2). Operating temperature: -20℃~+60℃
(3). Storage temperature: -40℃~+80℃
(4). Relative humidity: 10%~90%
Intrinsic safety explosion protection loop system
Special requirements have to be confirmed before using the intrinsically
safe explosion loop system(intrinsically circuit) which connected by isolated
barrier and intrinsically safe apparatus in field:
(1) The explosion level of intrinsically safe apparatus should meet the
requirements of operation conditions. The apparatus should pass the
explosion protection test and get the certificate by state-authorized
explosion-proof product certification bodies.
(2) The intrinsic safety parameters of isolated barrier and intrinsically
safe apparatus both are sure, and comply with 12.2.5 of GB 3836.15-2000.
(3)If any parameters are unclear, the system has to be confirmed by
state-authorized explosion-proof product certification bodies.
