18 Technical Manual | Dräger Polytron
®
8000 Series
Description
4.4 Intended use
The instruments of the Polytron
®
8xx0 family are intended for continuous
monitoring of the ambient air.
With the optionally integrated relay module, the instrument can be operated without
a control unit (with additional local alarm signaling).
With a sealed conduit or approved cable gland, the instrument can be connected to
a Dräger control unit or a Programmable Logic Controller (PLC).
If the 4 - 20 mA interface is used, the current between 0 and 3.5 mA must be
monitored. Currents between 0 and 3.5 mA can indicate a special state.
The instrument is designed to be installed in permanent locations and is approved
for use in hazardous, classified areas.
