Feature description

®
Polytron 5xx0 instruments are housed in a rugged stainless
steel or aluminum enclosure for indoor and outdoor
applications.
There are 3 main versions of the Polytron
®
– Polytron 5100 EC is intended for electrochemical
sensors (EC sensors).
®
– Polytron 5200 CAT / Polytron
catalytic Ex sensors (CatEx sensors) and infrared Ex
sensors (IREx sensors).
®
– Polytron 57x0 IR is intended for PIR 7x00 sensors.
Gas concentrations, status messages, and menu choices are
displayed on a backlit graphic LC-display and 3 colored LEDs.
With the non-relay version the red LED flashes to inform
visually and no relay is energized. To energize the A1 or A2
relay the optional relay board must be installed.
Navigation through the menu is done by taping a magnetic
wand on the glass at the appropriate indicator. The instrument
can be configured, calibrated and maintained non-intrusively
without declassifying the area.
The instrument can be operated as current source or sink.

Configuration possibilities

3.3.1 Interfaces

● 4 to 20 mA analog (per NAMUR recommendation NE43)
● Relay board

3.3.2 Explosion protection

®
The Polytron 5xx0 instruments are available in 2 explosion
protection types.
● Explosion proof instrument (Ex d)
The flameproof / explosion proof enclosure provides three
¾" NPT openings, which can be used for field wiring,
direct attachment of a sensor or wiring of a remote sensor.
● Instrument for increased safety (Ex e)
The instrument is extended by an increased safety
terminal box (docking station) that provides up to four 20
mm openings, which can be used for field wiring or wiring
of a remote sensor. The permissible cable diameter range
is 7 to 12 mm.

Intended use

The instruments of the Polytron
connected through a sealed conduit or approved cable gland
to a Dräger monitoring system or a Programmable Logic
Controller (PLC). With the optionally integrated relay module,
the instrument can be operated without a central controller
(with additional local alarm signaling).
For a safe operation in accordance with TÜV 19 ATEX 8435 X
, the connection to a central controller is necessary.
This also applies if all relays are connected because the fault
relay is not activated during maintenance. In any case, the
analog output must be monitored because it might indicate a
special status by a current between 0 and 3.5 mA.
The instrument is designed to be installed in permanent
locations and is approved for use in hazardous, classified
areas.
®
Polytron 5100 EC-specific:
®
– Polytron 5100 EC is a combined intrinsically safe /
explosion proof instrument for continuous monitoring of
toxic gases or oxygen in the ambient air.
®
Polytron 5200 CAT-specific:
®
– Polytron 5200 CAT with catalytic DrägerSensor DQ or LC
is an explosion proof instrument for the continuous
monitoring of combustible gases and vapors containing
hydrocarbons and non-hydrocarbons (e.g. hydrogen or
ammonia) in ambient air.
®
Polytron 5310 IR-specific:
®
– Polytron 5310 IR with infrared DrägerSensor IR is an
explosion proof instrument for the continuous monitoring
of combustible gases and vapors containing hydrocarbons
in ambient air.
