English–RTD-INTERFACE Safety Manual | 1
Introduction
The Druck RTD - INTERFACE/RTD - INTERFACE - IS is a
digital remote Resistance Temperature Detector (RTD)
interface. It is used with an RTD probe and a Druck
portable indicator or calibrator, for example DPI 705E,
DPI 705E - IS, DPI 620G or DPI 620G - IS.
These user instructions include the operations for the
RTD - INTERFACE/RTD - INTERFACE - IS, safety
instructions and the requirements for intrinsically safe
product.
The RTD
- INTERFACE/RTD - INTERFACE - IS is equipped a
standard M12 socket for connection of 2,3 or 4 wire RTD
probes.

Safety
The RTD - INTERFACE/RTD - INTERFACE - IS has been
designed to be safe when operated using the procedures
detailed in this manual. Do not use this equipment for any
other purpose than that stated, the protection provided by
the equipment may be impaired.
Before installing and using the
RTD - INTERFACE/RTD - INTERFACE - IS, read and
understand all the related data. This includes: all local
safety procedures and installation standards, and this
document.
The RTD
- INTERFACE/RTD - INTERFACE - IS may be used
with an M12 RTD probe directly plugged into the RTD port,
item 1 in Figure A3. Ensure that the touchable surfaces of
the RTD probe and
RTD - INTERFACE/RTD - INTERFACE - IS do not exceed the
following limits:
If the surface temperature limit is exceeded, use a suitable
M12 extension cable to bring the touchable surface
temperature back into limits.
The RTD probe used must be designed to withstand and
contain any pressure present in the media being
monitored.
Repair
Do not do repairs to this equipment. Return the equipment
to the manufacturer or an approved service agent.

Installation
These instructions detail the requirements for using the
RTD - INTERFACE - IS Intrinsically Safe RTD Interface in a
hazardous area. Read the whole publication before
starting.
•
Installation should be carried out by qualified plant
installation technicians in compliance with all local
safety procedures and installation standards. For
example: IEC/EN 60079 - 14, US National Electrical
Code NFPA 70 or Canadian Electrical Code (CEC).
• Provide additional protection for indicators that may be
damaged in service.
For an overview of the equipment connections, refer to
Figure A3 and the explanation below:
1. RTD port.
2. Electrical port.
RTD Connection
The wiring diagram for the RTD port, item 1 in Figure A3, is
shown in Figure A4.
WARNING
Do not use the non-intrinsically
safe RTD - INTERFACE in locations where
explosive gas, vapor or dust are present.
There is a risk of an explosion.
Some liquid and gas mixtures are dangerous.
This includes mixtures that occur because of
contamination.
It is dangerous to ignore the specified limits
(refer to data sheet) for the
RTD - INTERFACE/RTD - INTERFACE - IS or to
use the RTD - INTERFACE/RTD - INTERFACE - IS
when it is not in its normal condition. Use the
applicable protection and obey all safety
precautions.
HOT SURFACE
A RTD probe can be used
to measure a very wide temperature range.
Avoid freeze/burn hazards when installing and
removing RTD probes at extreme
temperatures.
Device Permitted Surface Temperature
RTD - INTERFACE -10°C (14°F) to +60°C (140°F)
RTD - INTERFACE - IS -10°C (14°F) to +50°C (122°F)
This symbol, on the equipment, indicates a warning
and that the user should refer to the user manual.
Ce symbole, sur l'appareil, est un avertissement qui
indique que l'utilisateur doit consulter le manuel
d'utilisation.
WARNING
Do not use tools on the sensor
that might cause incendive sparks - this can
cause an explosion.
