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.

Configuration / operating the function keys
Documentation for routing diagram.
In general
When configuring the 9202, you will be guided through all parameters and you can choose the settings which fit the
application. For each menu there is a scrolling help text which is automatically shown in line 3 on the display.
Configuration is carried out by use of the 3 function keys:
1will increase the numerical value or choose the next parameter
2will decrease the numerical value or choose the previous parameter
3will save the chosen value and proceed to the next menu
When configuration is completed, the display will return to the default state 1.0. Pressing and holding 3will return to the
previous menu or return to the default state (1.0) without saving the changed values or parameters.
If no key is activated for 1 minute, the display will return to the default state (1.0) without saving the changed values or
parameters.
Further explanations
Password protection: Programming access can be blocked by assigning a password. The password is saved in the device in
order to ensure a high degree of protection against unauthorized modifications to the configuration. If the configured
password is not known, please contact PR electronics support - www.prelectronics.com/contact.
Cable fault information via display front 45xx
Cable fault (see limits in the table) is displayed as CA.BR (cable break) or CA.SH (cable short-circuited). Cable fault is shown
independently for each channel but the configuration is common for both channels. In case of cable fault the backlight flashes.
This can be reset by pressing the 3key. When the cable fault has been remedied, the module will return to normal operation.
Advanced functions
The unit gives access to a number of advanced functions which can be reached by answering “Yes” to the point “ADV.SET”.
Display setup: Here you can adjust the brightness contrast and the backlight. Setup of TAG numbers with 5 alphanumerics.
Selection of functional readout in line 2 and 3 of the display - choose between readout of digital output or tag no. When
selecting ”ALT” the readout toggles digital output and tag no.
Password: Here you can choose a password between 0000 and 9999 in order to protect the unit against unauthorised
modifications to the configuration. The unit is delivered default without password.
Language: In the menu ”LANG” you can choose between 7 different language versions of help texts that will appear in the
menu. You can choose between UK, DE, FR, IT, ES, SE and DK.
Power rail: In the menu ”RAIL” you can choose if errors in the module are transmitted to the central surveillance in the PR
9410 power control unit.
Safety Integrity Level (SIL): See Safety Manual for details.
