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.

Modbus basics
Modbus is a “master-slave” system..., where the “master” communicates with one or multiple “slaves”.
The master typically is a PLC (Programmable Logic Controller), DCS (Distributed Control System), HMI (Human Machine
Interface), RTU (Remote Terminal Unit) or PC.
The three most common Modbus versions used are: MODBUS ASCII, MODBUS RTU and MODBUS/TCP.
In Modbus RTU, data is coded in binary, and requires only one communication byte per data byte. This is ideal for use over
multi-drop RS485 networks, at speeds up to 115,200 bps.
The most common speeds are 9,600 bps and 19,200 bps.
Modbus RTU is the most widely used industrial protocol and is supported by the 4511.
Modbus RTU:
To communicate with a slave device, the master sends a message containing:
Device Address - Function Code - Data - Error Check
The Device Address is a number from 0 to 247.
Messages sent to address 0 (broadcast messages) will be accepted by all slaves, but numbers 1-247 are addresses of specific
devices.
With the exception of broadcast messages, a slave device always responds to a Modbus message so the master knows the
message was received.
4511 Supported Modbus Function Codes:
The Function Code defines the command that the slave device is to execute, such as read data, accept data, report status.
Some function codes have subfunction codes.
The Data defines addresses in the device’s memory map for read functions, contains data values to be written into the
device’s memory, or contains other information needed to carry out the function requested.
The Error Check is a 16-bit numeric value representing the Cyclic Redundancy Check (CRC).
Maximum number of registers which can be read or written at once:
For a read command, the limit is 8 registers at a baud rate up to 38,400 bps, 16 registers @ 57,800 bps and 32 registers @
115,200 bps.
For a write command, the limit is 123 registers at baud rates up to 115,200 bps.
