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 self-
calibration, 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. 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.
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
This device is designed for connection to hazardous electric voltages.
Ignoring this warning can result in severe personal injury or mechanical damage.
To avoid the risk of electric shock and fire, the safety instructions of this manual 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 manual 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.
Warning
Until the device is fixed, do not connect hazardous voltages to the device.
The following operations should only be carried out on a disconnected device and under ESD-safe
conditions:
Dismantlement of the device for setting of DIP-switches and jumpers.
General mounting, wire connection and disconnection.
Troubleshooting the device.
Repair of the device and replacement of circuit breakers must be done by PR electronics A/S only.
Warning
SYSTEM 5000 must be mounted on DIN rail according to DIN 46277.
The communication connector of SYSTEM 5000 is connected to the input terminals on which dangerous
voltages can occur, and it must only be connected to the programming unit Loop Link by way of the
enclosed cable.
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. Warning/
demand. Potentially lethal situations.
The CE mark proves the compliance of the device with the essential requirements of the directives.
The double insulation symbol shows that the device is protected by double or reinforced insulation.
Ex devices have been approved according to the ATEX directive for use in connection with installations
in explosive areas.

Safety instructions
Definitions
Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and 50 to 1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and also trouble-shoot technically correct and in
accordance with safety regulations.
Operators, being familiar with the contents of this manual, adjust and operate the knobs or potentiometers during normal
operation.
Receipt and unpacking
Unpack the device without damaging it and check whether the device type corresponds to the one ordered. The packing
should always follow the device until this has been permanently mounted.
Environment
Avoid direct sun light, dust, high temperatures, mechanical vibrations and shock, and rain and heavy moisture. If necessary,
heating in excess of the stated limits for ambient temperatures should be avoided by way of ventilation.
All devices fall under Installation Category II, Pollution Degree 2, and Insulation Class II.
Mounting
Only technicians, who are familiar with the technical terms, warnings, and instructions in the manual and who are able to
follow these, should connect the device. Should there be any doubt as to the correct handling of the device, please contact
your local distributor or, alternatively,
PR electronics A/S
www.prelectronics.com
Mounting and connection of the device should comply with national legislation for mounting of electric materials, i.a. wire
cross section, protective fuse, and location.
Descriptions of input / output and supply connections are shown in the block diagram and on the side label.
The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power switch, it should be easily accessible and close to
the device. The power switch should be marked with a label telling it will switch off the voltage to the device.
Year of manufacture can be taken from the first two digits in the serial number.
Calibration and adjustment
During calibration and adjustment, the measuring and connection of external voltages must be carried out according to the
specifications of this manual. The technician must use tools and instruments that are safe to use.
Normal operation
Operators are only allowed to adjust and operate devices that are safely fixed in panels, etc., thus avoiding the danger of
personal injury and damage. This means there is no electrical shock hazard, and the device is easily accessible.
Cleaning
When disconnected, the device may be cleaned with a cloth moistened with distilled water.
Liability
To the extent the instructions in this manual are not strictly observed, the customer cannot advance a demand against PR
electronics A/S that would otherwise exist according to the concluded sales agreement.
