6 Product Pillars

to meet your every need

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.

Individually outstanding, unrivalled in combination

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 self­calibration, sensor error detection, low drift, and top EMC performance in any environment.

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.

We provide inexpensive, easy-to-use, future-ready communication interfaces that can access your PR installed base
of products. The detachable 4501 Local Operator Interface (LOI) allows for local monitoring of process values,
device configuration, error detection and signal simulation. The next generation, our 4511 Remote Operator
Interface (ROI) does all that and more, adding remote digital communications via Modbus/RTU, while the analog
output signals are still available for redundancy.
With the 4511 you can further expand connectivity with a PR gateway, which connects via industrial Ethernet,
wirelessly through a Wi-Fi router or directly with the devices using our Portable Plant Supervisor (PPS) application.
The PPS app is available for iOS, Android and Windows.

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.

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.
Our backplanes further simplify large installations and provide seamless integration to standard DCS systems.

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.

Warning

To avoid the risk of electric shock and fire, the safety instructions of this guide must be observed and
the guidelines followed. The specifications must not be exceeded, and the device must only be applied
as described in the following. Prior to the commissioning of the device, this installation guide must be
examined carefully. Only qualified personnel (technicians) should install this device. If the equipment is
used in a manner not specified by the manufacturer, the protection provided by the equipment may be
impaired. Until the device is fixed, do not connect hazardous voltages to the device.

To avoid explosion and serious injury: Modules having mechanical failures must be returned to PR
electronics for repair or replacement.

Repair of the device must be done by PR electronics A/S only.

In applications where hazardous voltage is connected to in-/outputs of the device, sufficient spacing or
isolation from wires, terminals and enclosure - to surroundings (incl. neighboring devices), must be
ensured to maintain protection against electric shock.

Potential electrostatic charging hazard. To avoid the risk of explosion due to electrostatic charging of the
enclosure, do not handle the units unless the area is known to be safe, or appropriate safety measures
are taken to avoid electrostatic discharge.

Symbol identification

Triangle with an exclamation mark: Read the manual before installation and commissioning of the

device in order to avoid incidents that could lead to personal injury or mechanical damage.

The CE mark proves the compliance of the device with the essential requirements of the directives.

Ex devices have been approved acc. to the ATEX directive for use in connection with installations in

explosive areas.
