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.

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.
The device must be installed in pollution degree 2 or better.
The device is designed to be safe up to an altitude of 2 000 m.
The device is designed for indoor use.
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.e. wire

How to dismantle system 2200
Picture 1:
The back panel of the module is detached from the housing by way of a
screwdriver.
Picture 2:
After this, the back panel can be pulled out together with the PCB, but
please notice the position of the PCB as there is a number of different
positions in the house. Do not pull the wires unnecessarily, instead pull the
PCB.
Switches and jumpers can now be moved.
When assembling the back plate and housing, please make sure no wires are
stuck.

Switchmode power supply 2222
• 230 or 115 VAC primary voltage
• 24 VDC output voltage
• Double isolation by 3.75 kVAC
• 48 Watt output power, short circuit-protected
• Thermal protection against overload
• DIN rail mounting on a standard 11-pole relay socket
Application
• General 24 VDC supply for equipment that requires a stabilised DC voltage.
• Separation of circuits in safety installations according to the PELV/SELV norm.
• Two units can be connected in series to achieve a plus / minus supply or a higher output voltage.
• The small mechanical dimensions of the switchmode power supply allow for a high DC output power, even in narrow
spaces.
Technical characteristics
• The power supply is based on primary switchmode technology to achieve a high efficiency.
• Galvanic isolation between the primary and the secondary voltage is achieved through the double-isolated safety
transformer. A thermal fuse protects the input circuit when the internal temperature exceeds 100°C.
• A 1 A fuse on the input protects the switchmode power supply against a short overload.
• The DC output is protected against a short circuit by an electronic current limiter that activates at an output current of
2.5 A.
• A green LED on the front of the module indicates an active primary voltage.
Mounting
• To achieve maximum cooling of the module, mounting in a vertical position at a distance of minimum 10 mm between
neighbouring units is recommended.
Input
• AC power supply according to the specifications.
Output
• DC voltage of 24 V. An internally mounted potentiometer allows for a ±5% adjustment of the output voltage.
