4511 Communication Enabler

PR Electronics 4511 signal converter communication module provides local and remote access to monitor, simulate and configure process values for the 4000 and 9000 signal conditioners. Local operation is simple with three pushbuttons and an LCD display with scrolling text, in 7 languages, which guides the user effortlessly through all the configuration steps. Three remote connection methods provide a flexible choice of communication.


The 4511 offers four ways of interconnectivity;
1. Showing process values on the local display, with the ability to simulate, monitor and configure process values on-site.
2. Connecting to Modbus RTU devices, either individually or in parallel by Modbus RTU (RS485).
3. Connecting to many major communication protocols via gateway to convert the ModBus RTU signal to any other communication protocol.
4. Using the PR Electronics PPS app on a tablet or PC to access values remotely.


For new or existing installations of the various PR Electronics 4000/9000 signal conditioning devices, the 4511 represents an easy way to go digital. Not only is it cost-efficient and safe, but it is also easy to implement and use.

The 4511 programming interface simply snaps on without the need for tools. The 4511 instantly detects the device settings and process values, while the intuitive, fully programmable front display and remote communication options make signal conditioning simple. Once connected the 4511 interface is used to set or modify operational parameters, simulate inputs and monitor devices, all while maintaining connected equipment.

Save time by saving an existing configuration in the 4511 programming interface and load that configuration into a similar 4000 or 9000 series device by following a few simple steps.


The 4511 programming tool lets you perform digital calibration on the 4000 and 9000 series as well as the 3114 unit with a few simple pushbutton actions. Guided by a simple step by step on device menu, you can opt for a full calibration (low/high), or a single high or low calibration.

Connecting the 4511 to the 4590 ConfigMate (7967039) interface allows direct connection to a PC providing several options:
• Print calibration and configuration reports directly from the computer
• The report shows the pre-calibration error to 5 decimal places
• You can add a wealth of information to the calibration report: technician's name, tag number, serial numbers of test equipment used, and much more.

Features and Benefits

• Easy and intuitive connectivity
• Modbus RTU protocol interface over RS-485
• High 2.5 kV isolation to host unit
• Shielded RJ45 connector on top
• Auto discovery finds your 4000 or 9000 devices once paired
• Simultaneously obtains both analogue and digital signals
• Provides redundancy or additional measurements to ensure stable and secure data availability
• Powered via the connected signal conditioner
• Password protection ensures protection against unauthorized modifications to the configuration

Mounting / Installation

The 4511 programming display simply clicks onto the front of the signal conditioning device. Once mounted the 4511 interface automatically energises and establishes a communication link. The device is now ready to configure the selected signal conditioning module.

To remove the programming interface push the release button on the bottom of the device and swing upwards. The programmer can now be clipped to any other 4000 or 9000 series signal conditioner.
