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.

HAZARD-
OUS
VOLTAGE
INSTAL-
LATION
GENERAL
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
To keep the safety distances, devices with two built-in relays must not be connected to both hazardous
and non-hazardous voltages on the same device’s relay contacts.
SYSTEM 2200 must be mounted in socket type S3B Releco (order no 7023).
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 EU directives.
The UKCA mark proves the compliance of the device with the essential requirements of the UK
regulations.
The double insulation symbol shows that the device is protected by double or reinforced insulation.

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

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.

Current limit: Max. 26 mA.
Standard voltage output (pin 2) is obtained by leading the current signal through an internal shunt resistor.
With internal dipswitches a 50 Ω or a 500 Ω shunt resistor is selected, which results in a voltage output of 0...250 mV and 0 /
0.2...1 V (50 Ω) and 0...2.5 V and 0 / 2...10 V (500 Ω).
With a special internal shunt resistor, units with other output voltages can be delivered (max. 12 VDC).
Current and voltage signals are referring to the supply gnd. but if both signals are used simultaneously, only the voltage signal
has gnd. as reference.

Programming / operating the function keys
Documentation for routing diagram
The programming is menu-controlled. The main menus are numbered in level 0 (x.0), and the submenus are numbered in level
1 (x.1 to x.5). Each submenu has an accompanying entry menu. The menus are structured in such a way that the menus most
frequently used are closer to the default menu 0.0. Please note that programming is only possible when submenu 5.4 PAS has
the value 040.
Main, sub-, and entry menus are selected by the 3 function keys 3, 1and 2as
outlined in the routing diagram.
Activating 2in the submenus will display the current value of the entry and
parameter selection menus.
In entry menus, the digit that can be changed will flash.
Active digit position is shifted by the 3key, and the value is changed by the 1key.
When the decimal point flashes, its position can be changed by the 1key.
In entry menus with fixed parameters, you switch between the parameters by the
1key.
Save by first activating 3and then 1simultaneously.
To return to the previous menu without changing the parameters, activate 2.
