Individually outstanding, unrivalled in combination
With our innovative, patented technologies, we make signal conditioning smarter and simpler. Our portfolio is composed of six
product areas, where we offer a wide range of analog and digital devices covering over a thousand applications in industrial
and factory automation. All our products comply with or surpass the highest industry standards, ensuring reliability in even
the harshest of environments and have a 5-year warranty for greater peace of mind.

Our range of temperature transmitters and sensors provides the highest level of signal integrity from the
measurement point to your control system. You can convert industrial process temperature signals to analog, bus or
digital communications using a highly reliable point-to-point solution with a fast response time, automatic self-
calibration, sensor error detection, low drift, and top EMC performance in any environment.
Temperature

We deliver the safest signals by validating our products against the toughest safety standards. Through our
commitment to innovation, we have made pioneering achievements in developing I.S. interfaces with SIL 2 Full
Assessment that are both efficient and cost-effective. Our comprehensive range of analog and digital intrinsically
safe isolation barriers offers multifunctional inputs and outputs, making PR an easy-to-implement site standard.
I.S. Interface Our backplanes further simplify large installations and provide seamless integration to standard DCS systems.

We provide inexpensive, easy-to-use, future-ready communication interfaces that can access your PR installed base
of products. All the interfaces are detachable, have a built-in display for readout of process values and diagnostics,
and can be configured via push-buttons. Product specific functionality includes communication via Modbus and
Bluetooth and remote access using our PR Process Supervisor (PPS) application, available for iOS and Android.
Communication

Our unique range of single devices covering multiple applications is easily deployable as your site standard. Having
one variant that applies to a broad range of applications can reduce your installation time and training, and greatly
simplify spare parts management at your facilities. Our devices are designed for long-term signal accuracy, low
power consumption, immunity to electrical noise and simple programming.
Multifunction

Our compact, fast, high-quality 6 mm isolators are based on microprocessor technology to provide exceptional
performance and EMC-immunity for dedicated applications at a very low total cost of ownership. They can be
stacked both vertically and horizontally with no air gap separation between units required.

Isolation

Our display range is characterized by its flexibility and stability. The devices meet nearly every demand for display
readout of process signals and have universal input and power supply capabilities. They provide a real-time
measurement of your process value no matter the industry and are engineered to provide a user-friendly and reliable
relay of information, even in demanding environments.

Temperature range programming

Please note:
• 3101 and 3111 - only TC input available
Valid TC J range: -100...+1200°C = correct DIP-switch setting
Valid TC K range: -180...+1372°C = correct DIP-switch setting
• 3102, 3112 and 3333 - only Pt100 input available
Valid Pt100 range: -200...+850°C = correct DIP-switch setting
• ”Start temp” must be lower than ”End temp” = correct DIP-switch setting
• Power must be cycled after DIP-switch positions are changed

The device is an Open Type Listed Process Control Equipment. To prevent injury resulting from accessibility to live parts the
equipment must be installed in an enclosure. The power Supply unit must comply with NEC Class 2, as described by the
National Electrical Code® (ANSI / NFPA 70).

For safe installation, the following must be observed. The device shall only be installed by qualified personnel who are familiar
with the national and international laws, directives and standards that apply to this area.

The devices shall be installed in a suitable enclosure providing a degree of protection of at least IP54 according to EN IEC
60079-0, taking into account the environmental conditions under which the equipment will be used.

When the temperature under rated conditions exceeds 70°C at the cable or conduit entry point, or 80°C at the branching point
of the conductors, the temperature specification of the selected cable shall be in compliance with the actual measured
temperature.

To prevent ignition of the explosive atmospheres, disconnect power before servicing and do not separate connectors when
energized and an explosive gas mixture is present.

For installation on power rail in Zone 2, only Power Rail type 9400 supplied by Power Control Unit type 9410 is allowed.

Do not mount or remove devices from the power rail when an explosive gas mixture is present.

In class I, Division 2 or Zone 2 installations, the subject equipment shall be mounted within a tool-secured enclosure which is
capable of accepting one or more of Class I, Division 2 wiring methods specified in the National Electrical Code (ANSI/NFPA 70)
or in Canada in the Canadian Electrical Code (C22.1).

The 3000 System Isolators and Converters must be connected to limited output NEC Class 2 circuits, as outlined in the
National Electrical Code® (ANSI / NFPA 70), only. If the devices are connected to a redundant power supply (two separate
power supplies), both must meet this requirement.

Where installed in outdoor or potentially wet locations the enclosure shall at a minimum meet the requirements of IP54.

Warning: Substitution of components may impair suitability for zone 2 / division 2.

Warning: To prevent ignition of the explosive atmospheres, disconnect power before servicing and do not separate
connectors when energised and an explosive gas mixture is present.

Warning: Do not mount or remove devices from the power rail when an explosive gas mixture is present.
