What is a panel meter?
PR electronics' range of digital panel meters and displays provide operators with clear, immediate, and accurate visibility of their process status. Typically mounted in control cabinets, these process indicators display live measured values, ranging from simple 4...20 mA loop-powered indicators to highly flexible, programmable devices.
More than just meters, these are robust industrial devices designed for reliability and ease of use in demanding environments, providing the crucial local visualization needed for troubleshooting, manual control, and enhanced operational awareness.

Universal and programmable for maximum flexibility
The cornerstone of our display range is flexibility. Our universal, programmable displays, such as the PR 5714 and PR 5725, accept a wide variety of input signals, including mA, V, Ohm, RTD, TC, and potentiometer. This versatility allows a single display model to be used across many different applications, simplifying inventory and procurement. With programmable inputs and outputs, these devices can be customized to meet specific process needs, providing a truly universal solution for process indication.
Clear and readable in any condition: LED and LCD options
We offer both LED and LCD technologies to ensure optimal readability in any industrial setting. The 57xx series features large, 4-digit, 14-segment LED displays that are easy to read from a distance and in various lighting conditions. For applications where power consumption is a concern, the PR 5531 series of loop-powered LCD indicators offers a low-power solution that is clear and easy to read in well-lit areas. All our displays are designed to fit the 1/8 DIN standard for easy panel mounting.
Simple and safe: Loop-powered and ex-approved displays
For simplified wiring and reduced installation costs, our loop-powered displays, like the PR 5531A and PR 5531B, require no separate power supply. We also offer displays approved for hazardous areas, demonstrating our commitment to safety.
The PR 5531A is approved for Zone 2 / Div. 2, while the PR 5531B is approved for the more stringent Zone 1, ensuring safe and reliable operation in potentially explosive atmospheres.
Advanced features for enhanced control
Our displays go beyond simple indication, offering advanced features for enhanced process control. The PR 5715 Programmable LED Indicator, with up to four relay outputs, can be used for local alarm and control functions.
Many of our displays also feature analog retransmission, allowing the process value to be sent to a secondary control system like a PLC or DCS. Additional features like multi-point linearization for non-linear signals and a scrolling help text for easy configuration further enhance their functionality.
Designed for industry: Easy configuration and 'Install & Forget®' reliability
Ease of deployment is a key feature of our display range. Configuration can be done via built-in push buttons on the front of the unit, PC software, or DIP switches. All our displays are built on our "Install & Forget®" philosophy, featuring high galvanic isolation, immunity to electromagnetic noise, and a 5-year warranty. This ensures a reliable, long-term solution designed for the rigors of the industrial environment.

What types of process displays does PR electronics offer?
PR electronics offers two categories: loop-powered LCD indicators (PR 5531A for safe area/Zone 2, PR 5531B for Zone 1) that display the process value directly from the 4-20 mA loop without requiring an external power supply, and programmable LED indicators (PR 5714, 5715, 5725) with 14-segment LED displays that accept multiple input types and provide relay and analog outputs. The LED indicators are 1/8 DIN size (48 x 96 mm panel cutout: 44.5 x 91.5 mm) and offer universal AC/DC power supply.
What input types does the PR 5714 Programmable LED Indicator accept?
The PR 5714 accepts current (0-23 mA), voltage (0-12 VDC), resistance (0-10,000 Ω), RTD sensors (Pt, Ni, Cu families), all standard thermocouple types (B, E, J, K, L, N, R, S, T, U, W3, W5, LR), and potentiometers (10 Ω-100 kΩ). This universal input capability means a single display model can be used across different measurement applications — temperature, pressure, level, flow — by simply selecting the appropriate input type and scaling during configuration.
What relay output functions are available on the PR 5714 and PR 5715?
The PR 5714 provides 2 relay outputs, while the PR 5715 provides 4 relay outputs. Each relay is independently configurable for setpoint alarming with adjustable hysteresis (0-100% of span) and ON/OFF delays (0-3600 seconds). The relays are potential-free contacts rated at 250 VAC/VDC, 2 A, 500 VA. Functions include high alarm, low alarm, window alarm (band alarm), and sensor error detection. This allows the display to serve as both an indicator and an alarm unit, eliminating the need for a separate trip amplifier in many applications.
What is the front panel protection rating of PR electronics display products?
When properly panel-mounted with the supplied rubber packing gasket, the PR 5714, 5715, and 5725 achieve an IP65/Type 4X front panel protection rating. This means the display face is protected against dust ingress and low-pressure water jets from all directions, making it suitable for washdown environments in food & beverage and pharmaceutical facilities. The rear of the unit (within the panel) is IP20. The overall display unit weighs approximately 230 g.
What display accuracy and update rate do PR electronics indicators provide?
The PR 5714 achieves accuracy better than 0.1% of the selected range, with a display range of -1999 to 9999 and a programmable decimal point. The display updates 2.2 times per second, providing a smooth, readable presentation of the process value. The signal-to-noise ratio is a minimum of 60 dB across 0-100 kHz. When the measured value is outside the configured range, the display shows explanatory text rather than a numerical value, immediately alerting the operator to an abnormal condition.
Can the PR 5531 loop-powered indicator be installed in hazardous areas?
Yes. The PR 5531A is approved for safe area and Zone 2/Division 2 installation. The PR 5531B is specifically designed for Zone 1 installation. Both variants maintain loop-powered operation, meaning no external power supply is needed in the hazardous area. When combined with an I.S. barrier (e.g., PR 9106B) in the safe area, the entire loop — from sensor through transmitter and indicator to the control room — can be operated intrinsically safe. This makes the PR 5531B particularly useful for local indication at the point of measurement in classified areas.
What certifications do PR electronics display products carry?
The PR 5714, 5715, and 5725 carry UL listing (UL 508, file E248256), DNV EU-RO marine type approval, CE marking per EMC directive 2014/30/EU and LVD directive 2014/35/EU, UKCA, EAC certification, Metrology Pattern Approval (MPA, Russia), and RoHS compliance per 2011/65/EU. The operating temperature range is -20°C to +60°C. These approvals make PR electronics displays suitable for marine, general industrial, and regulated metrological applications worldwide.
