It is fitted with a 16-key membrane keypad that provides distinct pressing feedback and high wear resistance, supporting frequent daily operations. In terms of storage configuration, it is built with 300 KB SRAM and 1024 KB FlashPROM, offering sufficient storage space for user control programs, process data, production recipes and system configuration parameters. A built-in hardware real-time clock powered by a lithium battery accurately records timestamps for production logs and fault records, facilitating equipment operation traceability and maintenance management.
In terms of I/O configuration, this model is equipped with 16 channels of 24 VDC digital inputs that support both sink and source modes, and 16 channels of 24 VDC digital outputs with a rated current of 0.5 A per channel. Each digital output channel is equipped with independent overload and short-circuit protection to ensure circuit safety. It also retains functional modules for 2 event counters, 1 incremental encoder interface or 2 gate/period measurement channels to meet diversified signal acquisition requirements. For communication, the device is provided with one galvanically isolated RS232 serial interface and one network-capable CAN bus interface, enabling stable bidirectional data exchange with external PLCs, servo drives, upper computers and other automation devices.
The rated working voltage is 24 VDC, with an allowable voltage fluctuation range of 18 VDC to 30 VDC to adapt to normal voltage variations of industrial power grids. The internal power supply circuit integrates comprehensive protection functions including overvoltage, undervoltage, reverse polarity, overcurrent and short-circuit protection to safeguard internal hardware components. The maximum power consumption of the whole device is 6 W, featuring energy-efficient operation. All finished products undergo full functional testing, display inspection, keypad testing, sealing test and continuous burn-in aging test before delivery, and hold CE certification to comply with EU industrial safety and electromagnetic compatibility regulations. It should be noted that TB718 terminal blocks (2 pieces) and TB103 terminal block (1 piece) need to be ordered separately for wiring.
Function and Positioning
Positioned as a highly integrated compact HMI and local PLC controller with pure digital I/O, the 4PP035.E300-01 integrates display, key operation, local logic control and data communication functions, undertaking core tasks such as on-site data visualization, manual operation and logic control in industrial automation systems.
In terms of human-machine interaction, the LCD screen continuously displays equipment operating parameters, process status, alarm codes and system prompts. The long-life LED backlight maintains stable brightness for a long time, ensuring clear reading in dim or strong light environments. The 16-key membrane keypad supports shortcut operations for common functions, effectively improving the work efficiency of on-site operators and enriching operation methods.
In terms of control and signal processing, the embedded 32-bit processor can independently execute user-programmed logic to complete sequential control, logic interlock and basic process regulation. The onboard digital I/O channels can directly connect field digital sensors and actuators, realizing on-site signal collection and action driving without additional external digital modules. It can work as a standalone compact controller for small and medium-sized mechanical equipment without an external PLC, or serve as a distributed local operation and control node in large-scale automated production lines, cooperating with the central control system to realize partitioned equipment management.
Through CAN bus and RS232 interfaces, the device uploads on-site collected digital signals and operating data to the upper management system, and receives control instructions from the upper system to drive on-site actuators. The highly integrated design reduces the number of discrete components and intermediate wiring, optimizes control cabinet layout, and lowers the overall system assembly cost and subsequent maintenance workload. It is a cost-effective and high-reliability front-end operation and control terminal, especially suitable for small and medium-sized automation solutions that only require digital signal processing and have simple to medium-complexity control logic.
Core Performance Parameters
Regarding display and operation performance, the 3-inch 160×80 pixel LCD display can maintain stable display effects and uniform backlight brightness during long-term continuous operation. The membrane keypad has excellent wear resistance, with sensitive and stable key response after millions of presses.
For electrical performance, the rated input voltage is 24 VDC, and the power circuit can tolerate voltage fluctuations within 18 VDC to 30 VDC. The maximum power consumption of the whole device is 6 W, achieving energy-saving operation. All communication circuits adopt galvanic isolation design to suppress electromagnetic interference from motors and frequency converters, ensuring accurate and uninterrupted data transmission. Each digital output channel has independent overcurrent and short-circuit protection, which can effectively avoid hardware damage caused by abnormal circuits.
In terms of environmental adaptability, the front panel reaches IP65 protection level against dust and splashing liquid, and the rear panel is IP20 protected. The rated operating temperature ranges from 0°C to +50°C, and the storage temperature ranges from -20°C to +60°C. It can operate normally under ambient relative humidity of 10% to 90% non-condensing conditions, with good moisture-proof and mildew-proof capabilities. The whole machine passes standard industrial vibration and impact tests, resisting mechanical vibration from running equipment without internal component loosening, display failure or key malfunction. The internal printed circuit boards are coated with conformal coating to further enhance anti-corrosion and anti-aging performance.
General Matching Accessories
For power supply and signal wiring, dedicated 24 VDC terminal blocks including 2 pieces of TB718 and 1 piece of TB103 are required, and these terminal blocks need to be purchased separately. In workshops with strong electromagnetic interference, shielded cables are recommended for CAN bus and RS232 communication lines to optimize signal transmission stability and avoid signal distortion.
Standard installation accessories include fixing screws and sealing gaskets, which are used for panel embedding installation and gap sealing between the device and the control cabinet. Users can select extended wiring brackets and cable management accessories according to on-site layout needs to arrange cables neatly and prevent cable pulling and wear during long-term operation.
