The internal power supply circuit is equipped with comprehensive protection against overvoltage, undervoltage, reverse polarity, overcurrent and short circuit to protect internal hardware. The whole machine weighs approximately 0.5 kg, featuring light weight and easy handling. 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 meet 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 mixed I/O, the 4PP035.0300-36 integrates display, key operation, local logic control, analog signal processing and data communication functions, undertaking core tasks such as on-site data visualization, manual operation, logic control, analog signal acquisition and transmission in industrial automation systems.
In human-machine interaction, the LCD screen continuously displays equipment operating parameters, process data, analog measurement values, alarm codes and system prompts. The long-life LED backlight maintains stable brightness for a long time, ensuring readable content in dim or strong light environments. The 16-key membrane keypad provides shortcut operation 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 analog I/O channels directly connect field analog sensors and analog actuators, realizing closed-loop control such as temperature regulation and pressure stabilization without additional external analog modulesB& R Industrial Automation. 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 touch screen uploads on-site collected digital and analog signals as well as 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 require both digital and analog signal processing and have simple to medium-complexity control logic.
