The B&R 4PP035.0300-01 is a compact Power Panel from the B&R 4PP series, integrating a programmable logic controller with a human-machine interface in a single space-saving unit. This device serves as a complete control solution for industrial automation applications, offering both visualization and control capabilities within a panel-mounted enclosure requiring minimal cabinet space. The 4PP035.0300-01 combines a monochrome LCD display, tactile keypad controls, and a powerful integrated processor, making it suitable for machine builders and system integrators across a wide range of manufacturing industries.

Technical Specifications

The Power Panel is powered by a 24 V DC supply with a nominal input range of 18 to 30 V DC, and maximum power consumption is 6 W. The display is a 3.5-inch monochrome LCD with LED backlight, featuring a resolution of 160 × 80 pixels. The front panel includes 16 keys: 10 function keys with yellow LEDs, 3 soft keys, and a numeric system keypad with cursor block. The unit provides 16 digital inputs (24 V DC, sink/source) and 16 digital outputs (source, 24 V DC, 0.5 A per channel). Maximum total output current is 8 A. Memory includes 300 kB of user RAM and 1024 kB of FlashPROM. Communication is via RS232 (9-pin male DSUB, up to 115.2 kbit/s) and an integrated network-capable CAN interface. The unit includes two event counters and one incremental encoder input or two gate/period measurement functions on the first three input channels. Dimensions are 153 mm width, 120 mm height, and 46.1 mm depth. Weight is 0.5 kg.

Integrated PLC Functionality

The 4PP035.0300-01 features a real-time clock with nonvolatile memory and 1-second resolution, powered by a lithium battery (3 V, 950 mAh) that retains data during power outages. A watchdog timer ensures system reliability. The processor executes basic instructions with a 0.8 µs cycle time. The device supports up to 2 event counters, 1 incremental encoder input, or 2 gate/period measurement functions on the first three digital input channels. Overload and short-circuit protection are included on all digital outputs, with internal protective circuits (VDR). The unit is powered by 24 V DC and includes voltage monitoring (NMI triggered below 15 V DC).

Display and Operator Interface

The monochrome LCD display provides clear operator feedback in industrial environments. The screen includes both European and Cyrillic character sets. The front panel keys include 10 function keys with yellow LEDs for status indication, 3 soft keys for contextual commands, and a system keypad with numeric entry and cursor control. The keys use slide-in labels for custom user designation. The IP65 front protection rating (EN 60529) allows use in wash-down environments, dusty factory floors, and other demanding industrial conditions.

Programming and Software

The Power Panel is programmed using B&R Automation Studio, the unified engineering environment for all B&R automation products. Programming languages include ladder diagram, structured text, and function block diagram, following IEC 61131-3. The CAN interface supports network-capable communication for distributed control. The device includes diagnostic functions with status LEDs for I/O function per channel. The unit requires terminal blocks TB718 (two units) and TB103 (one unit) for power and I/O connections, which are ordered separately.

Applications

The 4PP035.0300-01 is suitable for small to medium automation applications where both operator interface and control logic are required in a compact space. Typical uses include packaging machinery (filling, sealing, labeling), material handling systems (conveyor control), food processing equipment, printing presses, and special-purpose machinery. The integrated PLC/HMI reduces panel space, wiring, and component count compared to separate controllers and operator panels.

Installation

The Power Panel mounts on a 35 mm DIN rail or directly to a panel using the integrated mounting clips. The front panel is designed for cutout mounting; dimensions and cutout details are provided in the user manual. Connect 24 V DC power to the designated terminals. I/O connections are made via TB718 terminal blocks (ordered separately). Shielded cables are recommended for encoder and other high-speed inputs. For IP65 protection, ensure the panel gasket is properly seated. Operating temperature range is 0°C to 50°C, storage -20°C to 60°C. Humidity tolerance is 10-90% (operating) and 5-95% (storage) non-condensing.

Environmental and Compliance

The 4PP035.0300-01 is CE, UKCA, and UL certified (cULus E115267 industrial control equipment). It is RoHS compliant. Operating temperature: 0°C to 50°C. Storage temperature: -20°C to 60°C. The front panel is IP65 rated; the rear requires installation in a control cabinet.

Conclusion

The B&R 4PP035.0300-01 Power Panel provides a compact, all-in-one control solution for industrial automation. Its 16 digital inputs and outputs, monochrome display, and communication interfaces make it suitable for machine builders seeking a space-saving alternative to separate PLC and HMI components.
